This past week was a busy one for the iPhone App developers as several Apps were launched or updated on the Apple store. Here are the more notable ones:

The AOL instant messenger for iPhone and iPod Touch was updated for the iPhone OS 2.0. Unlike the previous version, you can now use the AIM Blast to send IM to multiple people. But more importantly, the app is free and more stable, so you’ve got nothing to lose in that regard.

Astromo shows you the locatino of heavenly objects at a specific time. Pretty useless application but is one heck of a time killer! And you have tooth ache, it can help you forget about it. Believe me!

BlackJack 3 hand edition is the new version of this game for the new iPhone. The glitches that made the game crash are fixed now, and you can play up to 3 hands of BlackJack at a time. It’s only $3.99 which is not bad considering that some worse Apps average $9.99.

300 Bowl is now updated for the iPhone 2.0. The version has been improved for the new iPhone, and some of the glitches are fixed. Another cool game.

Loan Calculator is not such a special App really if you think about it. But it’s a simple way to figure out how much your loan payment will be while you are on the go. I know some of you don’t need a calculator to get the number but this is still cool for the rest of us.

The most useful App in my mind is one that allows you to interact with services that you use on an everyday basis. Flickr is one of them for me, so when I saw Mobile Fotos. These guys use Flickr API to allow you to upload or browse photos on Flickr. This is not the official flickr App.
