Hi there, I have some problems when gaming on the iPhone, especially games that use the accelerometer. For example, 'Cube Runner' (free on the App Store): I put the iPhone on a flat table, I launch the application and start the game: the ship goes left! [isn't it supposed to go straight!?] Another example: 'Aqua Moto Racing' (free on the App Store): I repeat as above, and the water bike goes left... So, what can I do? If I go to a genius bar, they're going to fix it even if I have these problems only with non-Apple applications? Thank you.
