Ok guys, be easy on me. I rooted and put a lagfix on my Vibrant but I want to get into custom ROMs and learning how to properly backup my phone. Here are my questions. 1) What exactly are ROMs and are there any Froyo ROMs yet? 2) Do ROMs have the chance of bricking your phone? 3) What the eff is a "Nandroid" backup as opposed to a regular backup? 4) Since I have rooted and want to use a custom ROM, will I still get the official Froyo update? (when it finally comes) If you can answer each question seperately (by number) that would be GREAT!
