Guys.. I got an iphone3gs fr maxis which had just past its 1 year warranty and it got intermittent signal/service. Asked maxis sc and they qouted me rm500 for exchange for a new one. Anyone experienced this. Any fix? Not sure if its hardware or software related. Just want to know my options. Haven't exchange the phone yet. Currently only using it as an ipod since got no coverage even at my place.weird it in certain places it work just fine.im on ios 4.3.3 jb.
