• Be a makeshift DJ. I have a lot of music on in my iTunes Library. If there's something I or my friends want, I'll buy it and add it to the collection. Because of that, I get asked "Can you bring your music to the party tonight." I used to say no, because I didn't want to play DJ all night and miss out on the party. Now, I can setup a network anywhere I go and control my iTunes Library directly from my iPhone with Remote.app -- even play requests during a conversation.
• Keynote presenters unite! Creating a wireless network on your Mac frees you to worry about your presentation not the availability of wireless in the lecture room. Setup a network, connect and you're swiping through your slides.
• Sync applications anywhere, anytime. Victor just pointed this out today... if you're in an airport and need to sync some information from a desktop app to your iPhone, you don't need to pay for the airport wireless. Syncing apps like Bento, MacGourmet, Things, TextExpander or any other apps that sync over the network can update whenever you want without issues.

I'm sure there are many more uses for this idea... those just name a few. Please read on for a step-by-step, illustrated guide to create a wireless network between your Mac and your iPhone (or iPod touch).

Stepping up to a shiny new 3GS? Thinking about selling your old iPhone on eBay or craigslist? Don't forget to wipe!

I buy iPhones from time to time to unlock and offer to our local customers. One such phone arrived today and I eagerly opened the box to get things prepared. After charging the dead iPhone for a while, I powered it on and was greeted with tons of personal information about the previous owner.

The phone was loaded up with three accounts full of literally thousands of emails, 107 contacts, 974 songs, a few dozen photos and a handful of apps -- all still happily filling the 8GB. There were faxed checks related to the previous owner's sales position, visual voicemails available to anyone's ears, and a huge log full of text messages.

The previous owner hadn't deleted anything before sending his iPhone off to a complete stranger! While I was taking care of that important step for him, I thought "This is a perfect opportunity to save some TUAW readers from this sort of embarrassment, not to mention potential ID theft, with a quick reminder."

Clearing all of the data from your iPhone was made simple with the 2.0 firmware update last year.

1. Go to Settings
2. Tap on General
3. Scroll all the way down and tap Reset
4. Choose Erase All Content and Settings
5. Confirm (twice) that you REALLY want to lose everything

Make sure you have it plugged in, as the process will take quite a long time, "about an hour" according to the warning. But, believe me, it is time well spent!

Once the process is complete, you'll be left with a "factory fresh" installation of the iPhone OS with no trace of you or your data, and you can safely sell it and upgrade to the latest and greatest model. Oh, and do me a favor -- if I'm the auction winner, include a working sync cable this time!

If you read my recent post about taking movies with the iPhone 3GS, you probably noted that I talked about the lack of editing capabilities on the iPhone with the exception of trimming the beginning and ending of your videos. What if you want to edit your movies, add titles or effects, or combine a bunch of short iPhone video clips?

Several of the comments left by TUAW readers asked the same question, and it's so easy to do that I decided to whip up a quick tutorial showing how this works. You probably have a tool on your Mac that can do the job for you with just a few clicks, drags, and menu selections. iMovie is the perfect easy tool for creating full feature films (just kidding) from individual scenes shot with the iPhone 3GS video camera. Here's how to do it.

Caveat Emptor: This is for newbies only. If you've been around, you probably don't need this.

When I bought my last Verizon phone, it came with about three quarters of a pound of paper housed in three manuals allowing me to find just about anything through the index. Yeah, it was overkill -- but at least I knew where to go to learn about an option or feature.

When I opened my iPhone 3GS, I quickly searched for the documentation to show me how use this puppy. All I found was an accordion-pleated piece of paper, titled Finger Tips, telling me all the wonderful things my new iPhone could do... but it was awfully skimpy on covering just how to do anything at all.

On the last page of Finger Tips there were some links to get more information. Following the links would give you almost what you need. But I question how using a software-based paradigm of digital manual delivery relates to a hardware-based product like an iPhone 3GS.

Perhaps that's why an industry has sprung up to print instructional books. David Pogue's massive 'Missing Manual' series speaks to my point. If a good manual were to be included in a hardware product, 'Missing Manuals' would be superfluous.

Apple's manuals have been shrinking for many years; they have come a long way from that of the Apple ][+, in which Woz printed the entire ROM code of its 6502 processor.

The Apple way is to compactly package hardware. This seems way more elegant than being handed a big honking box. But adding half an inch to the height of the iPhone box, to accommodate a concise manual, wouldn't damage the minimalist look.

I don't feel quite right about having paid a goodly sum of money for the box and then having to download a 213-page manual using my own resources. My preference would be to have a manual the size of the iPhone 3GS right in the box, for immediate reference. With that, I could get started right away. After all, if you buy a new piece of technology, you don't want to be slowed down by needing to download and possibly print hundreds of pages along with reading a bunch of sites. You just want to push some buttons and play.

For those who have either lost the brochure or want some more information, see below for links where you can get it. Of course, you can always start with the "iPhone Help" section under the Help menu in iTunes.

The 213 page manual for the iPhone 3GS
Quickstart guides for various iPhone 3GS features
A video guided tour of major features of the iPhone 3GS

And here are some other resources to get you started:
Macworld's App Guide: Searchable by category
19 instructional books on how to manage your iPhone
Apptism - catalog and reviews of over 53,000 apps
Macworld's general listing of 3.0 features
TUAW's iPhone 101 series

I'm sure that many more resources are currently being written, but the links above are more than enough to get started.

I wonder how many agree with me that leaving out a decent manual is a poor idea, and how many of you consider this a non-event.

I just bought my first iPhone, a 32 GB iPhone 3G S, and found that that there is an abundance of information out there covering just about every aspect of its use. As an iPhone virgin, most of this is new to me, but I'm sure it's old hat to most.

Apple, however, is set to sell over half a million new iPhones this weekend, so I'm sure there are a lot of virgins in my position. This post and maybe some to follow are not meant for anyone who is fluent in iPhone, but rather for newbies like me. So, skip this if you've been at the party for awhile, but if you just ripped open your iPhone box, read on:

Ringtones
I tried making a ringtone from iTunes, but when right-clicking on a song and choosing 'create ringtone' I found that only songs purchased from the iTunes store could be used, at least in iTunes 8.2. In reality you can make a ringtone from any MP3. You can find the easy steps here.

Double Contacts and Calendar Entries
After setting up MobileMe and syncing my phone the first time, I found that all my contacts and calendar entries had been duplicated so that there were two identical entries of everything. Our own Chris Rawson set me straight on fixing this. If you disable calendar and contact syncing from the iPhone, all the information brought in from MobileMe will vanish. Next, re-enable them and you will be asked if you want to merge the contact and calendar information with what's on the iPhone (which was brought in by iTunes). You do. And in doing so, the problem will vanish. This tip is not just for iPhone 3G S owners, it's also happened to previous iPhone users who updated to system 3.0.

Period Space Bar Trick
When writing an email, typing the period key on my iPhone 3G S often does weird things like jumping down a line or two, slowing me down to a crawl. Chris Rawson also came to my aid by telling me that when you reach the end of a sentence, double tapping the space bar displays a period. This is much quicker for me, and my typing is cleaner. I'm not sure about earlier iPhones but for the iPhone 3G S, this must be set up manually. Go to settings-> general->keyboard and turn on the "." shortcut.

Applecare
There is no need to pay Apple $69 for AppleCare. I've been buying AppleCare from eBay at a decent savings for years. Often you don't get a full box, just a paper with the registration code, but I've never had a problem. Right now you can get AppleCare for $42 including shipping.

What have you found? If you have a problem or question and are too bashful to ask: ask here and we'll put our hive-mind right on it.

There's no denying it: locally caching messages in Gmail on the iPhone (via the storage capability in HTML 5, similar to Google Gears) is fun and good for you, especially if you don't connect to your Gmail via IMAP in the regular iPhone Mail application. Unfortunately, if the local copy of your mail gets funky, things can become difficult and much less fun.

John F. sent in this handy tip for resolving issues with cached Gmail; his suggestion is a quick dive into the iPhone's Settings app, then navigating to the Safari preferences to clear out the local database that stores the cached mail.

You may have to wait a bit the next time you connect to Gmail in Mobile Safari as the messages are re-downloaded, but any wacky cruft should be gone. While you're in there, take a look at some of the other settings options; you may discover choices you never knew you had.

This morning I opened my Mail inbox and was greeted with an email from a man who had read my iPhone articles in the premiere issue of iPhone Life magazine. He had a bunch of questions which, on first glance, appeared to be naive. However, I asked my rocket scientist wife (yes, she really is a rocket scientist!) if she knew the answers since she has had an iPhone for over a year, and she could only answer a few.

That's true not only of iPhone users, but of people who use any technology. For most people, just learning the minimal feature set is enough. It's when you decide that you want to learn more about how to use a particular feature that you can run into questions.

I often point people to Apple's excellent iPhone support Web site to get details on the minutiae of operating their iPhones. For those of you who are iPhone newbies or just afraid to ask, I've written up some answers to some common questions taken from the email and my reply to the reader.

Thanks to Fred for the inspiration!

Many websites and services offer great mobile versions without being packaged in an App Store application. If you want to be able to quickly access these sites from your home screen, follow these steps:

1. Launch Safari on your iPhone
2. Browse to a desired mobile site (most sites will automatically redirect you to the mobile version once they determine that you're using an iPhone)
3. Click the Favorites (+) button at the bottom of Safari
4. Click "Add to Home Screen"
5. Type a name for the icon that will appear on your home screen
6. Click the "Add" button

You will now see an icon on your home screen that will launch directly to the mobile website. Since I'm headed to Washington D.C. next week, I found this handy for the Metro mobile site and the Allpoint ATM search site.

One of the biggest comments on the recent SimCity announcement for the iPhone, other than being able to locate the SimCity International (link goes to the U.K. iTunes store) version of the game, was complaints that the game was crashing for some people.

This is not a new issue for graphically intense games for the iPhone and one of the solutions for solving this is very easy: Before playing your new game, reboot the iPhone.

Here's how to do it.

Update: As has been pointed out in the comments, a normal shutdown/startup process, or "soft reboot," should work fine: simply hold the power button down for 3 seconds and slide to power down. The "hard reboot" described here should only be used if your iPhone isn't responding to touches or the Home button -- it is not intended as regular maintenance. Thanks to all for the feedback.

[If your phone ever becomes completely unresponsive, you may need to do the 'hard reboot process described next -- but remember this is the equivalent of pulling out the power cord on your computer.] Hold down the Home and the Sleep/Wake buttons until your screen goes black, as shown at right. After a few seconds, you should see a sliding bar for powering off the phone. Ignore it and keep pressing those buttons. After about 20 seconds or so, the screen will go completely black and the silver Apple logo appears.

Once your phone goes through the rebooting process, launch your game. You shouldn't have any further problems with it. One word of warning: Rebooting the iPhone does drain your battery somewhat, so if you're pretty low on power you may find yourself unable to use the phone until after you're recharged it.

I saw this tip posted on the App Store when I was purchasing Scrabble at the end of November and followed the advice and didn't have a single problem with Scrabble on my 1st generation iPhone. I repeated it with SimCity and, again, I'm not having any issues playing the game.

If that doesn't solve your issues, check out this list of iPhone troubleshooting tips.

If you're like me, then you have around 7 home screens. It's annoying to flip back and forth between them to find the Apple apps, which are normally stored on the first home screen.

With the introduction of the new iPhone/iPod touch 2.2 firmware, you now have the ability to jump to the first home screen with one click. No matter which screen you're on, just click the home button again. You will instantly be shuttled back to the first screen. Now you'll never have to flip again.

Are you worried that your iPhone or its data might get stolen? If you are, then this post is for you! Let's take a look at the iPhone's security options, starting in Settings > General > Passcode Lock.

If this is your first time visiting the Passcode Lock settings, then you will be prompted to create a 4-digit passcode -- this can be anything, just make it memorable. Once you've entered and confirmed your passcode, you will see a couple options. The first two buttons let you turn the passcode lock off, or change your passcode.

The next option, called "Require Passcode," allows you to set the interval between which your iPhone will require you to enter your passcode. For instance, if you set this interval for 5 minutes and you "sleep" your iPhone, you will be able to wake it and start using it again (without entering your passcode) for up-to five minutes after you put it to sleep. After the 5-minute time period has passed, your iPhone will require the passcode upon waking.

You also have the ability to turn SMS Preview on/off. By showing the SMS preview, the sender's name (or number) and a few lines of the message will be displayed. If you have this option turned off, you will only see the generic "1 New Text Message" on the wake screen.

For more protection, enable the "Erase Data" option. This erases all data from the device if someone tries to enter the wrong passcode more than 10 times.

With the passcode lock turned on, you have the peace of mind that comes with knowing your device, and data is safe. When you wake your iPhone by sliding a finger to unlock it, you will be presented with a number pad to enter your 4-digit code on. Upon successfully entering your code, the home screen will be displayed. Note that this works for the iPod touch as well.

Many iPhone users use a Bluetooth headset on their phones. However, they may not know that you can use the same headset to listen to their Visual Voicemail.

To listen to your voicemail through your headset, just navigate to Phone > Voicemail. Once there, click the "Audio" button in the top right -- you will be presented with some options. If you have your headset paired with your iPhone, you will see a headset option along with the iPhone and Speaker Phone options.

Clicking any one of these will immediately transfer the audio to the output specified.

Thanks for the tip, Brandon!

With the advent of firmware 2.1, Apple has added the ability to pause a App Store download currently in progress. When you purchase an app, a temporary download icon will appear on your home screen. While the application is still in the download process, tapping it will pause the download.

Paused downloads will be denoted by the word "Paused" underneath the icon. To resume the download, just tap again. While Apple has added this feature to the iPhone OS, your mileage may vary as far as it working properly. In one instance, our iPhone had to be restarted completely before the download would resume properly.

When Apple first introduced the iPhone, they also announced a new set of earbuds to go along with it. These headphones sport a nice clicky button that allows you to pause/play/skip a song. However, they forgot to include a function to go to a previous song.

If you are running the new 2.1 firmware, you are now able to triple-click the friendly button on your headphones to go to a previous song.

We here at TUAW understand that the feat of creating a single button that serves four purposes is not an easy one. Therefore, join us in giving Apple a quick, but much needed round of applause for finally adding this feature.

Rearranging the icons on the home screen of your iPhone is a part of the customization fun that Apple built in. However, if you rearranged your icons and want them back to factory specifications, it is as easy as a simple tap. Just navigate to Settings > General > Reset. Once there, select the "Reset Home Screen Layout" button. A dialog will pop-up asking for a confirmation.

Once you return to the home screen, you will notice that all the icons are placed just like they were when you first turned on your iPhone! Third-party applications' icons will follow the default applications.
