Okay so I've been seeing a lot of people mentioning that they are running 2.1 and I'm really curious to know why they are running an older version of the os when 2.2 brings a whole lot of improvements. Is there something about 2.1 that you cant get on Froyo? Does 2.2 not run well on your phone? Post it up in the thread. Maybe someone will have a solution to the problems you had with Froyo and/or maybe you can talk someone else into running 2.1!
