Yeah but the JTAG is an unrealistic solution. It involves people actually opening up their devices... lol.
Anyway, if you have TEP, I'd honestly just call Asurion and pay the 50 dollars. You're gonna have much less hassle than dealing with Sprint. Asurion was real painless when my 6700 went out... at least as far as getting me another 6700. The fact that the 6700 I got was still jacked up is besides the point.
