Recently, we reported on AT&T's push to make it easier for iPhone & iPod touch users to connect to their Wi-Fi Hot Spots. One of our readers, Jamie Phelps, pointed out on his blog that AT&T's Wi-Fi service is not actually a "secure connection," as is advertised in various places on their website; we had overlooked this, and mistakenly reinforced the company's shaky claim in our post.

This brings to light an important point about wireless networks and security, however. It's really easy (and sadly all too common) to hop on to an available wireless signal in your office, at the hotel, or your favorite coffee spot and not even think twice about logging in to your e-mail or checking your bank balance.

What many users don't realize is even though the server you are connecting to (i.e. your bank's website) may employ several layers of security, the connection between your computer and the wireless access point is very likely to be unsecured. Anyone who is within range of your computer can trivially monitor the traffic being sent between your computer and the access point, allowing them to see what websites you may be visiting or capture details about other services that you may be connected to. This isn't because of some gaping vulnerability or software bug, it's just an inherent part of how wireless networks work.

So, what can you do to protect yourself? Read on for a list of simple steps you can take to ensure that your wireless connection is safe and secure.

Recently I spent a few days in Paris, France. I travel light: One bag (pro tip: Roll your clothes), one jacket and one hat. I love getting my necessities down to a single carry-on bag. What I hate is all the paper. Airline confirmation receipts, bus schedules, relevant correspondence from family and friends, etc. Not to mention lists of restaurants to try, sights to see, etc.

This time I went nearly paper-free (I'm sticking with paper boarding passes for international flights, although iPhone scanning has been done and is now officially supported by some carriers), thanks to my iPhone and 2 applications. Here's how I did it.

Tracking flights

Of course, the first thing I've got to do is line up all of my flights. I typically go from Boston to Newark when I'm traveling internationally, which means there are several connecting flights to manage with Flight Update and Evernote.

Flight Update [App Store link] is among my top 5 iPhone apps. Here's how it works and why I love it. First, add a trip and then add your flights. You can designate a preferred airline if there's one you use often. Enter your flight number and date (or search by route if you prefer) and Flight Update fills in an incredible amount of data as if by magic.

You'll get airtime, departing and arriving airport, terminal, distance, scheduled meals and so much more. It even identifies the type of plane and offers a color-coded seating chart (the colors rate the seats by desirability). You can even search for alternate flights should a problem arise.

What I really love about Flight Update is that it consistently beats the airport at dispensing timely information. For example, the flight I took from Newark, New Jersey to Boston, MA this past Monday was listed as delayed on my iPhone before the announcement was made at the gate. When the delay was later lifted (thank goodness), my iPhone let me know before the airport did. That's awesome. At $4.99US, you simply can't beat Flight Update. Every iPhone-toting traveler ought to own it.

Eliminating paper

With Flight Tracker handling the airplanes, I turned to Evernote [App Store link] to handle the paper. This is straightforward: I made a notebook called "Paris" and filled it with:

• Confirmation codes for each flight, including the original emails as PDFs
  
• Hotel information
• Correspondence from family members I'd be traveling with
• Special instructions

With each one tagged "Paris," I simply created a saved search. Here's how. First, enter your search term. Next, click the little blue arrow, scroll down and select "Save Search." From then on, you can access all documents that meet your criteria (in my case, a single tag) by hitting the bookmark button. In fact, I just left it there for the duration of my trip.

When I checked in at the airport kiosk, I simply grabbed my confirmation number from Evernote. Same with the hotel. When I found the restaurants and other points of interest that I wanted to explore, I snapped a photo note and applied the "Paris" tag. Back at the hotel, everything was sent to the Evernote servers via the free WiFi.

This has been said before, but Evernote (free from the App Store, basic and premium plans available) is awesome. Human beings have short term memory, long term memory and now, Evernote.

Keep in mind

Going paperless isn't without risk. There's a good chance that your airport will have a lousy cell signal and no free WiFi. Having to pony up $5 or so just to get a code is a hassle if you forgot to sync before leaving the house. Additionally, not all ticket agents are tolerant of kids these days with their fancy smart phones, and may give you an odd look (or a hard time) when you say, "I don't have the printout, but I have my iPhone!" Hence my hesitation to abandon paper boarding passes.

Finally, Evernote displays PDFs as attachments, meaning you can't view them without an internet connection. If you think that might be an issue, copy and paste the text itself into a note.

In the end I had a very enjoyable travel experience with just a small bag, my wallet and my iPhone. Here's a huge thank you to the developers of Flight Tracker and Evernote. Your apps are awesome.

As noted by our commenters below, you may also get a travel boost out of the Tripit app, which Steve reviewed not long ago.

It has been a busy few days for Apple in the software update domain. iWork '09, iTunes, and Quicktime have all been updated, along with GarageBand.

Today, Apple is pushing out an Airport Utility software update. With the usual great and patented Apple detail, the update:

"..includes general fixes and compatibility updates for the following applications: AirPort Utility and AirPort Base Station Agent. The update also installs AirPort Disk Utility on Macs running Tiger." There is also an update of the Airport Utility for Windows.

The new software is 18.9 MB, and does not require a restart. Hooray.

Thanks to Mikey for the tip.

Petre asks:

I just bought a new guitar and I'm thinking about using it to record some of my songs with my new iMac. Any recommendations for a good method of connecting a guitar so I can record?

Fortunately, you're in luck, in that the Mac is made for people trying to do just what you want to do. There are several options to accomplish this and it really just depends on how good you want the audio to sound and what your budget is. To get the best possible quality, you're going to need a few items.

First, you're going to need some recording software. Fortunately, that's already on your iMac as you can use Apple's GarageBand for all your entry-level recording needs. Second, you'll need some sort of digital audio interface that connects your guitar's output to a USB or Firewire interface on your iMac. Some good ones to take a look at include the M-Audio MobilePre, the M-Audio Firewire Solo or the Line 6 Tone Port series. Then, all you need to do is plug your guitar into the converter and the converter into your Mac and you're good to go. Of course, you'll want to be sure and update the driver to the latest version and read the manual to get the most out of your converter.

If you're not as concerned about audio quality, you can also use a converter cable, such as the Monster iStudio Link, to connect your guitar directly to the mic input on your iMac. That will allow you to record directly into your Mac but won't give you the best possible audio quality or level of customization you could get from a digital converter.

Apparently, to go along with today's hardware updates, Apple has also pushed down a number of updates via both Software Update and at Apple's Support Download site. The updates include:

• iPhoto 8.0.1 which "improves overall stability and addresses minor issues in a number of areas, including internet connectivity, keyword import, and slideshow export."
• iLife Support 9.0.1 which "improves overall stability and addresses a number of other minor issues. It is recommended for all users of Aperture, iLife '09, and iWork '09."
• AirPort Client Update 2009-001 for Intel Macs, which "addresses issues with roaming and network selection in dual-band environments."
  
• AirPort Utility 5.4.1 (Mac) for managing the Airport Express, Extreme, and Time Capsules.
• AirPort Utility 5.4.1 Windows - ditto for the dark side.

Check your Software Update or download them direct from Apple. Unfortunately, this set of updates will require a restart.

Apple released AirPort Extreme Update 2008-003, but then pulled it several minutes later. The update now no longer shows up in Software Update, and the page it was on is missing from Apple's site.

The update was originally recommended for all Intel-based Macs with Mac OS X 10.5.5. The update said it resolved "some issues with AirPort connections when roaming in large Wi-Fi networks."

The file was available from this page on Apple's website, and via Software Update. It's unclear why the update was pulled, or if there are any consequences for those who have installed it already.

If you installed the update, do you notice anything amiss? Let us know by leaving a comment.

Thanks, Danny and Randall!

I was in Anaheim, CA over the weekend (covering BlizzCon for our sister site WoW Insider) and while Macs were in short supply for most of the time, I did notice something Apple-related in LAX on my way out of the city yesterday. Best Buy recently started up a vending machine program which allows you to buy their electronics from staffless machines in various airports around the country, and lo and behold, right there next to the Nintendo DS games and spare USB hubs and mice, were Apple's very own iPods. Which makes sense -- Apple has long sold their stuff inside Best Buy stores, so why wouldn't Best Buy Express do the same?

It was a little strange, though -- at first, I thought there was an iPhone in there, which just would have made the whole activation process even more confusing. But no, it's an iPod touch, in both memory sizes. I also wondered just what you'd do with an empty iPod on a trip, business or otherwise, but I guess people who would really buy their iPods from airports probably don't worry too much about when they'll find the time to get music on there. Not that it mattered much yesterday -- as you can see in one of the pictures, the console's IE version was bugging out, so no one was buying anything anyway (and I couldn't check prices). Still, very strange.

Apple has released AirPort Utility 5.3.2 for Leopard. According to the release notes, the package includes AirPort Base Station Update 2008-002, and applies general fixes and compatibility updates for AirPort Utility and AirPort Base Station Agent.

The update is available via Software Update, or from Apple Support Downloads.

Thanks everyone who sent this in!

If I had to pick one feature of the Airport base station that makes me absolutely tear my hair out every time, that feature would be WDS. Getting a wireless network extended across multiple base stations with no wired interconnect is dark magic, and it seems like it never works the same way twice; it's always a mystery blend of MAC address input, switching between encryption modes, hard restarts, matching security settings and swearing. When I had to link up an Airport Extreme with two Airport Express units last week, I resigned myself to a long afternoon of trying to tame the user-hostile.

This time, though, it was different -- thanks to the power of N. 802.11n, now supported on both the Extreme and Express models, provides a remarkably easier WDS setup than earlier protocols. Rather than having to set the MAC addresses of the remote base stations and restart in sequence, on an all-n setup you just check the "Allow this network to be extended" on the master, and choose "Extend a wireless network" on the remotes. Easy as can be, and compared to the old way it's a big relief.

Along with the Keynote update, today Apple posted an update for the Graphite and Snow AirPort Admin utility. You can read more information about this Admin Utility update on the Apple support website; in a nutshell, it adds Leopard compatibility -- a good thing.

If you want to download the update, you can either open Software Update (Apple menu > Software Update) or download the installer package from the Apple support downloads site.

Note that he newer AirPort Utility (v5.3.1 or later) should be used for Time Capsule, and for AirPort Extreme or AirPort Express Base Stations. The update here is for the older base stations' admin tool.

Thanks to everyone who sent this in!

Quickertek has produced an antenna for the Time Capsule which, according to them, increases the device's range by 50%.

It's compatible with 802.11 A, B, and G, and comes either as a self install kit or an installation service. Or, if you don't have a Time Capsule just yet, you can order one from Quickertek with the antenna pre-installed. It comes with a good amount of cable so you can spend your weekend obsessively placing and replacing it in your home until it's just right. So that will be fun.

The 500GB self-install kit is $129.95US, and the service is $200US. Prices are the same for the 1TB version kit and service. If you want to do it all in one fell swoop, you can order a 500GB Time Capsule + pre-installed kit for $500US, or $700US for the 1TB version.

Update 9 pm ET: Our comrade David Chartier from Ars Technica points out that the 7.1.3 firmware itself may not be necessary for the new functionality to work; he says he tested a 7.1 AEBS with a machine running Time Capsule & Airport 1.0, and Time Machine was able to see the remote disk. Other readers have reminded us that the disk must be formatted as HFS+ with journaling, and you may have to mount it in the Finder before Time Machine sees it. The freeware TimeMachineScheduler is disabled by this update, comments note.

Update 6:45 am Thursday: More comments point out that if you take a locally-connected Time Machine drive and attach it to an AEBS, you will be starting over with new backups (because the remote backups are stored on sparseimages, not as folders). Something to keep in mind if you already have a long backup history -- you might want to use a different drive.

Sometimes the fixes are subtle and quiet. Once TUAW reader Peder downloaded today's Airport updates and ran the utility, he noticed a new version of the Airport Extreme firmware queued up and ready (v7.3.1). When he installed and rebooted his AEBS -- which happened to have a USB hard drive hanging off of it... well, let him tell you:

After downloading the latest Airport-update I checked for updates for my AirPort Extreme. After upgrading to version 7.3.1, Time Machine recognised the attached USB-drive.

If this is a reproducible result -- this means you, everyone, go ahead and start testing this firmware! -- that means that the now-you-see-it, now-you-don't Time Machine to AirDisk feature of Leopard has finally arrived. Sure, the Time Capsule is a one-piece solution and quite economical, but for all the AEBS owners out there who have been waiting patiently, this would be a very nice bit of March madness indeed. [Response to "just-a-guy" below: Remember, this is the Airport EXTREME only; the Express doesn't support AirDisk at all.]

Seeing the same results as Peder? By all means let us know. He was kind enough to send us a few screenshots, see below.

AirPort Flow is a way to see all of your traffic flowing to and from your AirPort base station in graph form. The bit rates are retrieved by using SNMP (which means you must have an AirPort router that supports this and have it enabled).

The user interface for AirPort Flow nicely fits in with Mac OS X Leopard; as it was designed for Leopard. The display stays above all other windows so you can keep a check on the bit rate as you are working. AirPort Flow was recently updated to 1.2 which added the ability to check for the number of wireless clients connected.

You can download AirPort Flow from the Memention website for the lovely price of free.
