i am experiencing signal loss after i upgraded my 2G iphone to 3.0 using redsn0w...it was working fine for 2 days then suddenly i keep receiving sms notice on missed calls. the phone did not even ring. i tried calling myself but it seems like the phone is off and can hear the M1 (singapore) message but in fact i have at least 3 bars on it. about 5 minutes later i received a sms informing me of my missed call. i have no problems calling out but it seems like incoming is screwed up..

i also noticed that my batt have been depleting very quickly... within 6 hours the phone will be totally drained from full charge....no calls incoming or outgoing, only one or 2 sms notices.....my phone is hotter than normal.....what is happening to my iphone...

i tried jb again but still the same....can anyone help pls??
