There's a lot of buzz about iPhone IM clients.Other applications have gotten a lot of coverage for allowing iPhones to chat from their AOL, Google, ICQ, Jabber or a host of other screen names.

WhatsApp [iTunes Link] is different, calling itself an "iPhone-to-iPhone chat application" that provides direct messaging between iPhones. The application features push notifications and provides functionality similar to SMS.

So why bother trying it? The app makes it easy to chat with other iPhones with no need for screen names, logging in and out or the added cost of text messaging and cellular charges. It's a lot like an iPhone version of Blackberry's popular messaging service. You'll also quickly and easily be able to point out which of your contacts have WhatsApp installed. Even if you're offline, your messages will be saved until you're back online.

Other cool features include the ability to "Broadcast" or send a message to multiple users, emailing of your chat history and sound and visual badges to show your unread message count. Users can also see when their friends are typing as well as the last time they checked their messages.

WhatsApp is free "for a limited time" so head on over to the App Store and grab it.

Here's a few shots of the app in action:

Agile Messenger was recently updated to support iPhone OS 3.0's push notifications. The obvious comparison will be to BeejiveIM, since they both do the same thing: provide a multi-client chat app offering push notifications on your iPhone. We'll have a hands-on with Beejive later, but this is how Agile Messenger (iTunes link) works. Oh, and we're giving away five promo codes so you can try it yourself, just check the end of this post.

The first screen in Agile Messenger is a series of switches for each protocol supported. These switches make it easy to see what you're connecting to when you tap the Connect button. There's support for ICQ, MSN, AIM, Yahoo, Jabber and Google. You can only log in to one account per service, however, so if you have 2 Google accounts, you're going to log in to one at a time. I'm told they are working to change this.

Once you are connected, Agile sets your status to "Available." If you close out of the app the defaults will set your status to "Away," although I soon changed it to keep me available even if I close out the app. In addition to your status, Agile adds the "Mobile with AgileMessenger" message, which I could do without. You can change this behavior in the app's preferences but you can only toggle it off. If you want to change your status, you have to change each account separately, instead of one global change. That's a bummer. There's a setting to auto-connect in the preferences, if you'd rather skip a step.

Agile's menus use rounded rectangles everywhere, and pop up like the old VH-1 series, Pop-Up Video. It's a nice visual touch, and if you want to back out of a menu just tap anywhere else on the screen but in the menu -- slightly faster than a dedicated Back button. By using the pop-up menus you can drill down into anything, but mostly contact management and preferences. Once in preferences, the buttons become standard iPhone UI, which is good, because there are bunches of switches. Pictures of the preferences in the gallery.

I've used the IRC for at least 10 years, if not more, and I've utilized a range of clients starting with the stalwart mIRC for Windows. When I migrated my home system to a Mac, the IRC client of choice quickly became the open-source Colloquy. It was simple to use and easy to integrate scripting via AppleScript. I could easily join chat rooms across multiple servers

So, it should be no surprise that Mobile Colloquy [link opens iTunes] shares many of the same features as its desktop kin. We first saw Mobile Colloquy back in 2007 when it was made available via the Installer.app and it very much the same on the surface as its jailbroken predecessor. It's taken the promise shown back then and has turned into an excellent and stable release that's now available through the App Store.

One of the unique features is a built-in browser that will open links transmitted in a chat room or private message. The some of the pages opened through the link are not iPhone-optimized version, but the regular Web sites. I accessed the optimized versions of CNN and Google just fine through the built-in browser, but TUAW came up as the normal site.

The button on the bottom right of the browser will take you into Mobile Safari. There is no bookmark tool, you'll go into Safari to take care of that. The "Done" button closes out the built-in browser and returns you back to your chat. It's a very nice feature, but I wish you could bookmark links without having to open the same web page again in Safari - something that could be extremely tedious over the EDGE network. Another drawback is when you do choose to go into Safari, you will be knocked off the servers you were logged into. Give the client a few seconds for the servers to reconnect, then tap the name of the chat room you were in. You will get a prompt asking you if you want to rejoin it.

Another very nice feature is completion pop-ups for basic IRC commands, including user names of other people in the chat room. You can also use specialized commands, such as /google query and /wikipedia query, which will bring up results in the built-in browser. All chat rooms and private messages are gathered under one screen. You can set specific words to be highlighted and turn on an optional vibration when the word is used, such as your nickname. Colloquy can be used either in portrait or landscape mode as well.

Mobile Colloquy is available in the App Store for $1.99, and it's well worth the money.

New to the Mac? Welcome back to our Mac 101 series, which explores the basics of Mac OS X, provides tips and tricks, and dives into key features of Apple's bundled tools.

As a Mac user, you've got several options for chat clients -- Adium, Fire and IRC are all worthy -- but in this post we're going to focus on Apple's iChat.

Create an account

When launched for the first time, iChat will prompt you to create an account. You've got five options, namely

• MobileMe
• AIM
• Jabber
• Google's GTalk
• Jabber

Make your selection and enter your information. If you're new to instant messaging, simply click the "Get an iChat account." Now your account is ready to go.

Among my favorite features of some of the non-Apple chat clients: tabbed windows. This allows you to collapse all of your open chats into a single window. That way, there's no need to have two or more windows open. Here's how to enable this in iChat.

From the Preferences window, check the "Messages" tab. Next, select "Collect chats into a single window." That's it! Now, iChat will list all of your open chats in a drawer along side your chat window. To move from one to the other, just click your chat partner's name.

MobileMe account holders trying to contact Apple's email outage chat support service have been promptly and brutally cut off if they're not on Apple's list of the "1%" of users affected -- and in one case, even if they are.

Some TUAW readers have been in touch to tell us that when they tried to get chat support for MobileMe email, they were quickly given this automated (or hastily pasted-in) response:

"I'm sorry, according to our records, you were not one of the members affected by the email outage that began on July 18th. MobileMe Mail 24-hour chat support is a temporary measure designed specifically for users whose accounts were affected by that outage. For help, please visit http://www.apple.com/support/mobileme/ww for access to all of our support resources. I apologize for any inconvenience."

But one of our correspondents was doubly displeased, because he insisted he had been one of the 1%. But here was Apple telling him he hadn't -- and not giving him any chance to argue the matter.

It's that "according to our records" bit that seems to be the problem. What if Apple's records are wrong?

Thanks to Bill and Dom for the tip.

Adium, the tasty multi-client Mac chat app, is about to get even tastier: developer Evan Schoenberg announced today on the Adium blog that he's adding Facebook Chat to the ridiculously long list of instant messaging protocols already supported by the app. He even included a screenshot of the new protocol in action, seen on the right.

No word on when the new release will be available, unfortunately, but you can keep track at the Adium blog.

Thanks, Chris!

Personally, I'm an Adium user at heart -- iChat is super nice (especially for a built-in chat program), but it just doesn't have the features and customizability that that Adium does. But if you have to use iChat for whatever reason (easy video conferencing comes to mind) despite your love for Adium, then this mod, sent to us by reader Philipp, will probably come in handy.

It's called iChat Pro, and it basically simplifies your iChat window, squeezing out the borders and cutting the buttons at the bottom. I don't think you can change the colors and design of the display the way you can in Adium (it's been a while since I used iChat, and a quick browse through the preferences didn't reveal any options for that), but at least it looks a little more professional than the, let's admit it, a little goofy, default iChat GUI. iChat Pro is a free iChat mod from Infinise Design.

Skype, which has become my primary means of communicating with anyone not standing directly in front of me, has updated to version 2.7.0.257 with improvements, changes and a very, very long list of bugfixes.

I'm happy, possibly even thrilled, about an alleged improvement in video stability. If you've ever used the video features, you've probably noticed that, in numerous scenarios, Skype prefers to show up more in your crash logs than on your desktop. I haven't had a chance to fully test out the video portion of this update and the release notes simply refer to it as "improved stability", so I'm hoping for the best.

The 20+ bugfixes, by and large, deal mostly with errors I haven't run into and one grammatical correction to a dialog. Oh, and they fixed the language name for Belarusian, which could potentially appease 9,081,102* people.

Fewer crashes and proper grammar are tantalizing but, as is usually the case, I find the API additions to be the most exciting. The Skype API is AppleScript-able and fairly comprehensive. This update adds more interface access, new voicemail features, and a few intriguing looking options which I'll just have to play with to understand.

It would be nice if the updater built into Skype actually did what the name implies, but for now you'll have to head for the web page and get it yourself. Be sure to check out the release notes.

Equinux, makers of iSale, CoverScout and an interesting collection of other apps, was at Macworld demoing TubeStick, their TV receiver. Like El Gato's EyeTV, the TubeStick is a hardware doohickey with the TV parts inside (logically) and some software that lets you watch TV on your Mac. Unlike El Gato, however, there is a social aspect to TubeStick. Example: you can chat with friends who are watching the same thing. The CEO took us on a quick tour, which you can view after the break.

(Note: Equinux also gave us some show swag which we'll be giving away next week)

Flying out of beta status, Adium 1.2 made a full-fledged public release today. And we were just talking about the beta release right before Christmas... Starting with an improved menubar item and account management features, the new features and bugfixes in 1.2 get too numerous for this post, so be sure to head for the Adium blog to find out what's new.

I will go ahead and mention one improvement that I'm personally excited about: AppleScript support has been improved in the new build and we'll be seeing outside projects interfacing with Adium more easily now. Non-U.S. users will also want to take a fresh look at 1.2 as it now sports over a dozen localizations.

Adium 1.2 is free and available for download!

Thanks Samuel & Thomas!

Meebo, the reigning champion of web-based chat, has just released their entry into the iPhone app arena. I had a chance to speak with meebo's CEO, Seth Sternberg, earlier today about the release, and they truly do have a surprisingly innovating iPhone app on there hands. Simply point MobileSafari at meebo.com and the site will send you to the iPhone portal (a technique about which our own Scott McNulty had a few thoughts to share) where you can sign into any of Meebo's supported services - including AIM, Yahoo!, MSN and Google Talk - or you can sign in with an account you have already registered with meebo. From there, things get very interesting (note that the screenshot below was snapped in Camino since I'm just not cool enough to get Erica's iPhone screenshot utility up and running).


First, if you registered an account with meebo and added your credentials for one or more chat networks, you'll appreciate the fact that everything transfers over to the iPhone app. Custom status messages, your buddy icon, even the history from chat sessions on your desktop computer - they all appear in the iPhone app. Your buddies are listed alphabetically, but any current chats float to the top of the buddy list for easy access, and this is a bit of UI where meebo has some unique innovation going on: the entire iPhone meebo experience centers around a home screen that is your buddy list; it takes up the entire display, and it even rotates and scales gracefully for landscape mode. No tabs here, which can be a mixed bag for the experience.

Tapping on a buddy slides over to a new chat window with nothing but an icon to get back to your buddy list, a box to type in and the send button. Chat history (if there is any) populates pretty quickly, even over EDGE, which is an area that Seth said the company focused quite a bit: ensuring the entire app was light on data, simple to use and ultimately fast. Tapping the buddy list icon of course gets you back to the list, and any chats you started automatically float to the top. This is where the lack of tabs can be both a blessing and a curse: while the buddy list is nice and large, making it far easier to to read and navigate than any previous iPhone chat apps, it still takes at least two taps - not including any potential scrolling - to get out of a chat, back to the list and into another chat; more taps if you need to scroll. It's a unique approach to solving this kind of a problem, but ultimately, I think meebo made the right choice.

All things considered, meebo's iPhone chat app is hands down my new favorite. I haven't been chatting much on my iPhone yet, but meebo's streamlined experience, fast load times and easy navigation make this a slam dunk that has finally sparked my interest in trying out mobile chat. I was even more surprised about how well they've done on this 1.0 app when Seth shared that this is meebo's first mobile app of any kind. While the company has done web-based chat for years now, they've never ventured onto any mobile device platforms. That said, I think they just about knocked this one out of the park. If you own an iPhone and need to chat, meebo.com is easily one of the best options available.

Adium, the reigning king of 3rd party multi-network chatting on the Mac, has been updated to v1.1, but don't be fooled: even though it appears to be a minor x.1 update, there's a pretty significant list of changes here. Tabs seem to be all new, with the ability to move the tab list to any side of the chat window (top, left, right, etc.). Customizing Adium's menubar icon has also gotten a lot easier, now that it is an official xtra for which you can download new icons from AdiumXtras.com. DirectConnect over AIM - the feature that allows you to simply drag pictures into iChat windows and have them display in-line during a chat - should also work more reliably, and it is automatically initiated when needed now. Rounding up the list of major changes is a new ability to import iChat accounts, statuses and chat transcripts, helping Adium to become your central chatting hub.

Of course this isn't all, so knock yourself out with the complete list of changes if you're feeling adventurous. Otherwise, simply start up Adium to receive the auto-update notification or head over to Adiumx.com to download a fresh copy, and be sure to donate to the Adium crew (check the bottom of the page) for their fantastic work on a great chat app.

Thanks to everyone who sent this in.

While Meebo is still working on optimizing their web-based chat service for the iPhone, a new player by the name of eBuddy is joining the ranks of FlickIM, JiveTalk and Trillian Astra. Already doing business like Meebo as a web-based, multi-network chat service, eBuddy has just announced an alpha version of their iPhone-optimized chat app that is heavy on the features, though certainly a departure from mimicking the increasingly standard iPhone-ish UI. With support for AIM, Yahoo! and MSN (which I thought was now called Windows Live Messenger?), as well as text styling and the all-too-handy tabbed chatting, eBuddy definitely offers a powerful iPhone chatting experience - if you're willing to wait for the web app to load, that is.

Users can simply visit ebuddy.com on their iPhone to access the optimized app. Alpha tester beware though: eBuddy took a surprisingly long time to load even over my AirPort Express Wi-Fi, which makes me worry about testing it over EDGE.

Still, it's nice to have options for those times when Apple drops the ball, and eBuddy looks like one of the most feature-packed chat alternatives for the iPhone yet.

Thanks Chris

Chatterboxes of the world, unite! You have nothing to lose but your inability to IM from your iPhone. Cerulean Studios, maker of the popular Trillian multi-service IM client for Windows, is hard at work on the next version -- Trillian Astra, which in addition to being cross-platform will also include a full web interface to all of the social networking features present in the standalone app.

A wee birdie (thanks Victor) pointed us to this post on the Trillian Astra dev blog, which shows an interesting version of the TA web access portal. Seems that the code monkeys are psyched to do a carefully-designed Trillian Astra portal that is tuned to Safari for iPhone's specs... nice. Go ahead and sign up as an alpha tester if you wish, and do tell them that you are an iPhone owner, but note that it will be a few weeks before the iPhone UI is ready for test.
