I tried to reset it and still persists. It doesn't happen all the time but happens most of the time... I get delyaed messages and sending gets delayed too...like 30mins to an hour delay.. but if i put it on 3g network, it solves the problem. But i dont wanna be stuck on 3g so its verry annoying.. can anybody help me? Or does anybody have similar experience.. i just bought my phone last month.
