I am currently using an 8700c that was originally used on the cingular networked and unlocked. I am now using it on Rogers in Toronto. It was working fine for about 3 weeks, and last night, during the middle of a call, the call was dropped and the phone went straight to "Searching for Signal".. I preformed a soft reset with no luck, then a hard reset with no luck. Now all it says is "no signal." Does anyone know what the problem would be or how it could be resolved? Perhaps i need a different OS or something? I'm just confused as to how a call could just drop and no signal be found. Any help would be appreciated. Thanks!
