Report "Unlock code I bought a pantech c810 & want to unlock to use on T-Mobile. I bought an unlock code but does not appear to be correct The unlock code box only allows 8 characters & the code received has many many more characters. Question is: how many characters should the code be? & is there any special way to input other than install the T-Mobile Sim card, powerup & enter code & pin twice. I am also looking for codes to unlock my duo...hate at&t and want to use it with sprint...can anyone help me???"
