First of all, my uncle bought me this phone and I have no idea if its a RAZR or a RAZR maxx. On the back of the phone it says XT912, in the settings menu it says xt912 and RAZR Max. I read somewhere that the model number is for a RAZR, not a max. Also the battery is **** so I'm confused. Second how can I unlock the boot loader of above said phone? Third I need to use the phone on us gsm networks, if anyone can point me to a link that would be great.
