Here's the latest version of the Facebook app. The version number is 2.5.1. According to Facebook, the new features in this release are:

• Support for more languages including  Thai, Arabic, Vietnamese, Devanagari and Hebrew.
• Photo tags are now displayed
• Added ability to "Like" comments and photos
• Photo uploading supported on more phones including the Samsung Seek

I'm not sure which Boost phones it works on.  On my Rambler and i776 it installs and runs but most of the keys don't work and as a result there's no way to get past the login screen.  The previous 2.3 version didn't work on my phones either but BoostApps readers reported that it worked on the Incognito, Juno, Factor, Rant and Seek, so I'm hoping this one works on at least those phones.

" Works great. Connects quickly. Keys are mapped correctly.

The Bad: Upgrading to new version impossible thru Facebook as they blackball my phone. QWERTY symbols are wrong. You have to press SYM and use the Symbol list.

Overall, great replacement for launching the web browser all the time."

According to Facebook, the app lets you update your Status, view your News Feed, Inbox, and Photos, upload photos and find friends from your phone’s contacts. Not all features work on all phones

I'm not sure what, if any, other phones it works on. It doesn't work on my Rambler or i776, it runs but none of the keys work. If you try it on any other phones leave a comment letting us all know if it works. Update: reported to work on the Mirro, Seek and Rant. Photo uploading reported to work on Seek and Incognito

Nimbuzz is a multi-network (AIM, Facebook Chat, Google Talk, MSN Messenger, MySpace, Twitter, Yahoo) IM app. It was updated to version 1.93 last week. According to a post on the Nimbuzz blog the new features in this release are:

• Message Delivery Notifications will display checkmarks when your message arrives on your friend’s phone.
• Access to free avatars and bots via N-World.
• Clickable links inside the chat screen
• New way to insert emoticons : Open a chat -> Menu -> Insert emoticon -> Enjoy

I've never had much luck with Nimbuzz on my  Boost Mobile phones and this one is no exception.

On  my i776, it installs and runs and the keys are mapped correctly. I can log in but shortly after I do I get the message "Sorry we had to disconect you from Twitter. Please try again latter while we are looking into it." Most of the time after I get that message the app locks up, although occasionally I can get past that message and Nimbuzz works.

On the Motorola Rambler, Nimbuzz installs but is unusable do to key mapping issues.  The left softkey action is mapped to the right softkey. I can adapt to that but the right softkey is mapped to nothing which is not good as it's used as the Cancel key and to return from menus and chats.

Because the previous version of  Nimbuzz was reported to work on the i856, i776 and i465 I'm posting this one for users to try. Please leave a comment letting me know if it works on your phone so I can update this post. If it doesn't work for you, try version 1.9 which seems to be more compatible with Boost phones.

Multi-network (AIM, Facebook, Google Talk, MSN Messenger, MySpace, Twitter, Yahoo) IM app Nimbuzz was updated last week. The version number was bumped up  1.92 (from 1.9).  Dispite the insignifigant jump in version numbers that are some major new features in this release:

• Invisible mode – to appear invisible to your Nimbuzz contacts while you are actually online.
• New Notifiable icon - for contacts that have the app closed but are available via push notification or Ping.
• Mandatory phone number verification for chat-rooms
• Faster login
• Less data consumption We expect that on average you will consume 50% less data, and depending on how you use Nimbuzz, this could get save you an amazing 70% in data used.

The Nimbuzz blog has more details about 1.92.  Unfortunately for Boost Mobile users the new release has  issues  with many Boost phones.  On my i776, it fails to install with a Class Verification Error. On the Motorola Rambler, Nimbuzz installs but is unusable do to key mapping issues.  The left softkey action is mapped to the right softkey. I can adapt to that but the right softkey is mapped to nothing which is not good as it's used as the Cancel key and to return from menus and chats.

The good news is that based on testing by cornel.j 1.92 does work on the Motorola i856.  Which means it probably also works on the i9 and maybe other models.  If you try it and find it works on any other Boost phones besides the i856, please leave a comment so I can update the compatible phones list. If you try 1.92 and it doesn't work you can always go back to 1.9.

Here's the latest 2.6.0 version of WeBuzz.  New features are that it can optionally send your location in a message  and it can display the Daily Hadith (a saying by or about Muhammad).

WeBuzz is supposed to support  AIM, Yahoo Messenger, Google Talk, MSN Messenger, ICQ and Facebook , but I got connection errors with AIM and Google Talk. The app hung if I tried to connect to Facebook (I did use my Facebook username as you are supposed to).  I didn't try ICQ, but Yahoo and MSN seem to work.

Another bug is that on my i776 the Menu > Back function didn't work to go back to the menu and I had to kill the app with the red key and start over. Back worked on the Rambler. I don't remember as many bugs in the previous version so I'm not so sure this one is an improvement. It might work better on other phone models

Thanks to Cornell J for  alerting  me that Nimbuzz has been updated.  It's now up to version 1.9 (there was a short-lived 1.83 that I missed).

The biggest change for iDEN users is that the key mapping issues that plagued earlier versions have been mostly fixed.  The OK button still doesn't work (press Call in place of OK) and in some of the menus the right soft key (labeled "Back") doesn't do anything and you have to press the Menu key instead. But everywhere else in the app the soft keys seem to be labeled correctly.

The new version also seems to start up faster and load the contact list more quickly.  Supported communities are Windows Live Messenger,  Yahoo, Facebook Chat,  Google Talk, AIM, MySpace, Twitter and Hyves.

Update: uTweeteMe has been updated to version 1.3 alpha.  Because of changes Twitter made to the login process (OAuth is now required)  the previous version no longer works and you have to update to continue sing uTweeteMe. There's been a small enhancement. You can now view @Replies to you on their own page.

I've received a few requests for a better Twitter client than TinyTwitter. I just sent an hour looking at a bunch of them and frankly they are all pretty bleak.  The best of the bunch seems to be uTweetMe.

It's fast, all keys are mapped correctly and it's fairly full featured. You can view your Friends Timeline, Tweet, Retweet, Reply, send  DMs, view @Replies  and view sent and received DMs. There are templates if you are into Tweeting the same canned text over and over. Unfinished Tweets can be saved as drafts.  On the other hand there are a lot of things missing; you can't see  Avatars or Twitpics or follow people.  And words are split across lines rather than wrapping properly. You can't follow links in Tweets either, although this is a limitation of the iDEN Java run-time rather than UTweetMe.

The other Twittter clients I tried and rejected are:
Twitlet: limited feature set and ugly full justified timeline display.
Jitter: TinyTwitter with ads.
Twibble, Twim: Failed to connect.

If anyone knows of a better Java Twitter client please let me know in a comment. For now, the best way to do Twitter on iDEN phones is Opera Mini combined with a good Web client like Tweete.net or Dabr.co.uk

Nimbuzz released version 1.72 of their multi-protocol IM client for Java phones a couple of days ago. Unlike 1.7,which didn't install on iDEN phones, I had no problems running this latest version on my i776.

There are no new features in 1.72, just the always worthwhile bug fixes and performance improvements.

Supported networks are the same as in version 1.6, Windows Live Messenger,  Skype, Yahoo, Facebook Chat,  Google Talk, AIM, MySpace, ICQ, Twitter, studiVZ, shuelerVZ, Gadu-Gadu and Hyves. Update: Skype support as been removed at Skype's request.

Startup time, always an issue with Nimbuzz on the low spec i776, does seem noticeably faster. Other than that I don't see much difference. Off line Facebook friends are still listed in the buddy list as numbers instead of by name (their names do appear if they go online) and  the OK button and the soft keys are still mapped incorrectly.

Because of the messed up key mappings you need to:

1. Use the green "Call" key as the "OK" key
2. Use the right soft key for the left soft key's action
3. Use the menu key for the  right soft key's action
4. Exception : When entering text in native pop up windows,  the soft keys (labeled OK and Cancel) work as labeled.
