hi everyone, idk what is wrong, or if this is even something to worry about, but its weird and its bugging me. i have had my 2g ipod touch for at least a month, and haven't had any problems with it. well, i just noticed that for some reason(it never used to do this before) when i open an app and then close it, a small loading circle appears at the bottom left corner of the app. its there for about 3 seconds and then disappears, is this normal, or is it bad? like i said, its just a small loading circle, the kind with the little circles that make like a type of ring...thanks and any help is appreciated!
