Flick solves a lot of those issues. It seems to stay connected better to their server (Meebo disconnects you each time you leave the current window), and I can get SMS notifications of an IM if I'm doing something else on the phone. Flick just reconnects and gives you the IMs you missed while you were away.pretty much tried them all and beejive seems to be the most mature. I wish there was a way to enable a sound notification when you get a message. Also a way to just stay logged in when your phone is off would be really nice.
