Can i use the internet GPRS, EDGE, HSPDA, and 3g on my iPhone 3G?
Yes. GPRS, EDGE, HSPDA and 3G all work fine on your Phone. We are the only unlocking device on the market to day which allows the phone to use 3g data. All the other deviceson the market require you to turn off 3g on your phone before getting a signal. • About “no sim” The connection problem on the chip, There are six little metal pieces on the chip showing on the picture. “6 Metal pieces”, Recently we have been requested to make the chips soft and thin, It causes the electronic contact to be too flat and small, That’s why some iphone 3G have “NO SIM” problem, the reason is that the phone sim card and the unlock sim card are not connected, the basic solution is to make those 6 metal pieces and the sim card fully connected. For example, pressing into the card trough, the clean SIM card copper, ,make them completely connected, finally achieve the unlocking goal! We apologize for the inconvenience.
