I am running on a unlocked 2.0.1 2G iPhone and I think now is the time to make an effort and upgrade to 2.2.1. I have a few questions: Can I jump straight from 2.0.1 to 2.2.1? Is it as simple as last time? I have been reading alot of baseband warnings that I am not understanding. Will my cydia installed apps still work? (That is the absolute decision maker) Sorry for all the questions and just want to make sure thanks!
