@ coolshahul , man, this solution only if there is no network @ all or the signal is weak & of course before applying that solution it must be measured first & if it's broke then do it, the problem here signal OK just after power on the phone for few seconds then goes !!!

coolshahul · 09-30-2007, 17:46
