[Droid1]

Hey all - My wife and I just took the android plunge and got two gently used Droids off ebay. They were both running 2.2, but when I took them to get flashed over to Metro, the guy doing it at the store downgraded them to 2.1 running Smoked Glass v6.0. I want to know if I can upgrade the ROM now that it's already flashed and still be able to work on metro. I've got full internet, gps, mms (as long as I don't use the highest quality 5mp pics), talk, and text, and I don't want to mess that up, but I'm really not feelin the 2.1 smoked glass after having played with the 2.2 rom that came on the phones.

I've searched here, droidforums, howardforums, google, etc and the question's been asked but never answered - can I upgrade to a 2.2 rom without messing up the phone's settings?

Thx in advanc
