http://forums.androidcentral.com – i just flashed CM10 today and have no data service now. my phone thinks its roaming and will not connect to the network. everything else works fine. ive seached all day for a solution. im guesing i did something wrong when flashing the rom. i tried a few other roms and no luck. also, went back to the stock rom to see if it would help and it didnt. any suggestions? thanks.
