First Android is where its at. trust me most people who go from iPhone to Android love android and dont listen to the people who have a iPhone and go get a crappy old android, or they never even owned a android.

Second what carrier do you have if att a good phone is the pantech discovery all i see on the web is good reviews and if its verizon a razr m is good as they are both $50 with upgrade if you wanna spend more a htc one x and a razr HD are super good phones and if sprint a galaxy nexus or samsung galaxy s2 are what you want.
