i'm ready to leave my iphone and switch to an android but don't know what to buy. i like the razr maxx hd but searching online, ebay and amazon has me confussed with the different models, etc. can someon recommend something? i need "unlocked" and i'd like to stay under $200, love the body and style of the razy line. also, do i have to buy factory unlocked or can i buy a phone and unlock it myself to use on another no contract carrier? i appreciate any help or advice you can give. thanks!
