I've been using a jailbroken 3G running 3.1.3 for a few months now. I love winterboard and backgrounder (proswitcher), but I'm having trouble finding an IM client that I can leave in the background. I've tried Nimbuzz and Meebo. Meebo gets really buggy in the background, and Nimbuzz suffers from memory leaks that require periodic restarts to fix (I have to restart Nimbuzz about every 15-30 mins). I hate push notifications. I just want to send the app to the background, hear a beep or chime, and go back in to answer the message. Can anybody point me in the right direction? Thanks!
