if you look in this thread
http://forum.ppcgeeks.com/showthread.php?t=37509 you will find everything you want. in my experience, if you order through telesales there are going to charge the full amount to your card.. and then when they get the phone back they are going to reverse the diffrence back to your sprint account.. then you have to called them fight them to get it back on your card... if you can try to have them order it on your sprint account that way you don''t get screwd over.
