Our favorite instant messaging app for the iPhone and iPod touch, Beejive (pronounced bee-hive,) just got updated to version 3.0. While there are a few nice additions, the biggest is that Beejive now supports push notifications on the iPhone.  If you are unfamiliar, this means you can tell Beejive to stay persistently connected to Apple’s push servers, even when you close that app. So you can keep a conversation going, while you also check your email, surf the Internet, and more. If you get a new IM, you will get a text notification telling you so, which you can simply close, or use to launch Beejive and take you directly back to the conversation.

Seriously, if you want a downright amazing IM app on your iPhone, consider BeejiveIM.
