Iphone 3G 16GB - US Model. - Im currently using the model with a turbo sim.

The iphone been jailbreak using quikpwnd. and im using turbo sim fro network unlocker.

So far the phone serve me well. im not sure how long will it be. But as for 3G reception issue
and also other like call drop i do experience it since the 1st model of 2G 8GB model.
The network is up and down via maxis with iphone.

When ever i cant detect the 3G or Edge or GPRS, i just restart it and it will detect it again.
As far im concern - the 3G network signal dropping is still the problem face by other official
Carrier Unlock user..

All i can say - just pray for the dev team to come up soft lock for iphone 3G US Model.
