Are you a BlackBerry user addicted to instant messaging but hate that mobile chat eats batteries for breakfast? Constantly watching in the background for incoming chat requests tends to cause these programs to use battery power like crazy.

Shape Services IM+ All-in-One Mobile Messenger is the answer for instant messaging users — Push instant messaging. The way it works is when your BlackBerry chat closes Shape’s servers keep you logged in and send an email message whenever someone tries to chat. This prevents your BlackBerry from having to constantly poll the servers. They’ve also just added Facebook chat which so far is working well on my test device. Look for an updated iPhone IM+ version with Facebook chat as well. I’ll have more feedback later in the week. So far my impressions are very positive.
