No you are probably not doing anything wrong, but I have a question for you. You have a Moto V300 from Tmobile, and you have unlocked it so you can use it on Cingular? What SIM card do you have? Cingular or TMobile? This makes a difference. The other thing, is that because Cingular doesn't offer the V300 some of the features may not work correctly. Keep that in mind. Let me know, and maybe I can tell you more... Remember SIM card, CINGULAR or TMOBILE? This is my question.
