Problem with iPhone 4 (8 GB): the cell phone/SMS/3G function works intermitently...
Since 30 days ago, at least once per day I have to turn-off and turn-on the iPhone, and then it starts working again...
1. I changed the SIM card at a Koode service center
2. I restored to factory settings the iPhone
3. Apple changed me the iPhone for a brand new iPhone 4
It stills do the same thing...
Coverage is good: at leats four full bars. It is a big city (Quebec city).
Before, it used to work in this same city.
