Iphone 3GS keeps Restarting itself randomly
Hello,
Basically i am using a iPhone 3GS Version 4.1. It can boot up normally and every funtion inside works pretty fine. it's just that it only last for about 5 to 7mins.
After 5 to 7 mins it will make a restart randomly and after it restart i can use my phone again ... Why is this happening? Tried restoring didn't help I'm out of warrenty! Is there any solution??? Please help!!! Thank you!
