Well I haven't posted on here in months- and its great to be back. I have my iPhone 3GS registered to my own Apple dev account with OS 4.0. It has worked perfectly for a week now up until today. This phone will not stop rebooting itself randomly. When I'm using it, it reboots every 10-15 minutes or so. When its just in my pocket and I'm not texting or getting emails- no problems. So this is my cry for help. Does anyone else have any suggestions as to what to do? Anyone else experienced this problem with 4.0? Much thanks in advance.
