I jailbroke and unlocked my iphone 3G with ios 4.2.1 and BB 06.15 and everything worked great since I only had a voice and txt t-mobile plan. Now I switched to a prepayed t-mobile plan (which I strongly recommend) that has data (edge). I can't get data to work. It works fine on WiFi but not edge. I am positive I have all the Network setting configured perfectly. I have been able to figure out everything else on this phone by reading and hacking around but I am stumped. Please help me. Thank you.
