I have kind of a speculative question. Say I were to root, enjoy all of it and more, mess around for a while, then flash back to a 2.1 sbf, would I be able to get the 2.2 OTA update if I mine phone has already received the OTA update and I am running 2.2? So, in steps: Root Install ROMs and themes galore Flash back to 2.1 Check system update to see if I can download 2.2 OTA Will it work? Just a curiosity question more than anything. If you don't have an answer for this other than, "just stay rooted, you won't want to go back," please refrain from answering.
