I have been searching for the answer and no luck so far. I'm running Rooted Android 2.1 rooted with P3 1Ghz kernel and TI backup. I want to be able to run flash, Apps to SD, and restore my original apps I have backed up with TI back up. I've read a lot about options but cant decide on the safest path. Stock 2.2 will eliminate my root correct? I'm low on space and Apps to SD is my main concern. I'm happy with 2.1 at 1gz. Let me know what you guys think the best route would be.
