i have 2 of them but i bought them from a guy and when i tried to switch them to my account they told me that the guy i got them from owes a bill and i cant use them until he pays his bill or maybe in 3 months the esn will clear itself so be careful on what you buy check the esn before you but it all you have to do is take the battery off and call sprint and give them the esn and they will tell you if it is clear or not you might know all this allready but im just trying to keep people from getting burned like me.
