wm 6.0 downgrade Hi, I recently bought a q9c because I could not handle my treo 800w anymore... it is junk. Anyway, I was thinking about upgrading to 6.1, but am worried I might re-encounter issues I had with the treo. If I update and don't like it, can I do a master reset to get back to 6.0? Is there anyway to get back? Thanks.
