Hello, I'm new here, and I am in urgent need of help. I have an HTC Desire under U.S. Cellular, obviously American, and I've used up all of the internal memory, and I know that Android 2.2 can install Apps to the SD card, which is a real godsend. I love HTC Sense UI, and I also want to make sure this won't interfere with the carrier and the phone and all that, you know, so if I can root this thing somehow, and go to 2.2 while maintaining the HTC Sense UI, I'd be very happy. So the question is, how do I do this?? Thank you all very much for your assistance.
