1. ok so im rooted right now with fresh 2.1.2. and i was wondering if i ever had to bring my phone to sprint for a repair or anything, can i just load the 2.1 rom or the 1.5 stock rom onto my phone again to maake it seem like i never rooted? 2. if so, do i just flash it like i do with custom roms? 3. what is the difference between fresh 2.1.1 and 2.1.2.? 4. i know 2.1.2. is de-odexed and 2.1.1. isn't but is 2.1.1. just as fast? 5. what is the difference between damageless roms and fresh roms? which one do you prefer and why? sorry for the questions but i even looked these up and i couldn't really find any definitive answers.
