Hi, I just got my D2G. It's my first android phone, so Im kinda noob about all this. The device is unlocked but right now Im having problems trying to get 3g to connect. When I go to settings to pick my preferred network mode I pick: Only GSM, but when I go to GSM/UMTS options/settings the Only 2G box is checked, if I remove the check mark on the box the network mode changes to GSM/WCDMA... Whenever I change to the last option: Favorite GSM/WCDMA it connects to 3G for some seconds and then goes back to Edge. So, do I lose my unlock sbf ing the phone again? I dont know what to do.
