hey im new here, and I recently bought an iphone 4 and ive been dieing to use it! Its running on ios 5.0.1 and is jailbroken. after finding out i can not unlock it, i switched to h20, reading that you do not need an unlock by many people. i did have to cut the sim, so before i did i tested the sim on a 3gs with no unlock, and worked perfectly. but when i put it in the iphone 4 it gets stuck on no service. ive searched for the answers and havent come up with anything. Ive tried installing SAM but on itunes it still says that the phone cant recognize the sim card. Any other suggestions? anything would greatly help, thanks!
