I have sold my Droid (purchased a Fascinate) and I want to "clean" the phone for delivery to seller. I have removed all personal data from the sd card and removed various applications. The phone is rooted with UD v8. How can I "unregister" the telephone from Google so that my calendar and email are not downloaded to the phone? I want to keep the phone rooted but if I do a factory reset won't it remove root as well?
