I had a plan with sprint for 6 years, they were great to me but the past few months my bill sky rocketed and i am stuck with a 450 bill. i had the HTC evo and the HTC evo shift on my plan but it got shut off. so my gf went and got a plan in her name and got us 2 samsung nexus S's.... they suck compared to htc. i tried calling sprint and reading a few forums and i found out that the ESN is locked due to that bill i owe. i dont understand it though bc the F'n phone is mine i paid for it the day i got it why cant i use it however i want. so thats my question. is there a way i can swap ESN numbers between MY HTC evo shift and MY Samsung Nexus S
