iPhone 3GS connection issue
My problem is very intermitten. My phone will not send text messages, calls fail, and cannot connect to the internet. The phone is displaying all bars, the ATT logo, and 3G. sometimes restarting the phone fixes the problem for a short time sometime restarting it does nothing. Sometimes after restart the phone spends sometime "searching" for a signal. All other aspects of phone including Wi-Fi work normal. Any assistance would be appreciated.
