Last year when WP7 came out I went out and bought a new HTC HD7 ran great up until mango and the device stared to crash out every other day to the point where it had to be rolled back. T-MO sent me a replacement ON/off button does not work when it's charged the battery has to be pulled in order to use it. want to put it in sleep mode nope pull battery it's a mess talked with T-MO we don't have any devices you send you..huh? we can send you a radar with a new contract.NO..NO..NO... so i have that insurance and blow this up you have to replace it right.. yes... well then why can't you send me a replacement then? we can't we don't have anymore. but wait you have them on sale right now on-line.. those are new devices.. Oh so the replacement ones are the ones that people send back because they are defected and you guys turn around and send them out to folks like me right....This fight is on going. with some higher up manager suppose to call me tomorrow rubbish. seams to me if they can't replace it then they kill the contract not I.
