The same the day bought my SII for metro I installed CM10 on it. Little did I know the guy at the store set my phone # wrong and everytime I call "voicemail" and other apps recognize another phone number, but when I call people it shows the right number. So the problem is that it is displaying the wrong number. All I want to know is if someone can help change it without having to go back to stock, since the service codes from stock don't work (I called metro, the codes they gave me did nothing. Was a very awkward situation since the woman seemed to not even know what android was.) TLDR: I need the service codes on CM10 to change my Phone Number.
