That's the only thing I dislike about this phone. Some apps if left open will kill the battery in a short amount of time... I guess I wil have to be more diligent with my apps...
If you have At&t, and your phone is in stock condition, you will have 6 at all time. The 5 listed above plus PTT.
Also note, that some third party apps add an icon to that list and can't be closed all the way either. The only ones I know of are MobiPocket Reader and Empower Email Viewer or BB Smart Email Viewer, but I am sure there are more.
In most cases, hit the "C" button, it should take you right to "Close".
Thanks. I tried the C button but it selected "Compose Email" first. But if I press it again, it selects the next option on the menu that starts with a C, and eventually makes it down to the Close button! Thanks for the help and inspiration there
