Iphone 3g 3.0 suddenly loses then gains signal.
Ive got an issue with my iphone. Its a 3g, recently upgraded from 2.2 to 3.1 software and its unlocked with ultrasnow. and on o2 uk
Ever since i upgraded it, the phone suddenly loses signal so that the o2 bit is still showing and the bars are empty for the signal bit, and it doesnt say no service, sometimes searching. Then 5 seconds later it will suddenly go back to normal full signal.
Ive never had problems with signal and still now i dont, its always full signal.
it occurs every 10 mins when i use the phone, and sometime when i slide to unlock, but it will interrupt calls and tethering and everything that requires signal.
Has anyone else had any issue like this before? Or know of anything that i can do without reinstalling the software?/
Thanks for any help
