When I turn AIM off by closing it is multitasking bar, I still get banner notifications when I get AIM messages on my desktop. When I check the multitasking bar, AIM isnt there. I think this might be a reason why battery life is an issue for some. There are a lot of background apps continuing to be run even when they appear to not be running. If I reboot the phone, then it works but once AIM is loaded, it never turns off. Having to turn off notifications off on the app after closing the app is a PITA. Hope apple fixes this soon.
