I do it, but I am in the HRM and rarely if ever get to Truro area, plus theres quite a bit of equipment involved with the 360 to mod it..
Go here and look to see what tray you have, thats the first step... All models are currently moddable except for the BenQ drives that came out late last year. Make sure you get V5.3 if you have samsung drive, or V1.7/2.4 if you have hitachi drives... these fix the disc jitter issues that MS is currently scanning for with Live and Backup play.
