I bought my new 3G iPhone last Friday and it is a joy to use. Well, until I realized that the "accelerometer" does not work as it should. I have restarted the iPhone 5 times in less than 48 hours to make it work. The pictures would not moved, nore the calculator, for example, when I tilt the iPHone.
So I made a restore from iTunes, nothing changes the situation. The accelerometer works fine after a restart. It works OK for a few minutes then, after the iPhone went on sleep mode,it does not work anymore.
Any idea of what I should do (except calling apple ?)
