My beautiful white iphone has been working flawlessly since I got it on launch day. Battery life was fabulous, no pixel problems, great reception, etc. I've just noticed over the last day or so that my tilt feature is severely lagging and sometimes not even working at all. I've tested it in both safari and ipod for the album coverflow. I'll be using it in portrait mode, will turn it to landscape...sometimes it will take about 5-6 seconds to turn and sometimes not at all. I'll have to exit out of safari and go back in for the screen to turn. Has anyone else has this problem? Is this a effect that the people complaining about lag are having? I dont know what would be causing this, but dont know if its something significant enough to take into Apple to have them look at. I love my phone in every other way though.
