I noticed the other day that when i put on an app , or my sms, phone, safari, whatever i tap on, the app will load fully on the screen and then for a slight fraction of a second, will adjust a little more, i dont know if this is something that has always happened, but ive never noticed it before, and its now starting to annoy me. i went to the apple store in london and they wouldnt see me, as i had to book an appointment with the geniuses. has anyone else had this problem? help will be appriciated, thanks, btw i have a 3gs.
