for those of us who rooted our pro's and disabled a lot of bloatware, should we restore the apk's before upgrading to gingerbread? and can we leave the phone rooted?
You need to restore any frozen/removed stock apps and you need to unroot before installing any updates. People who tried to install the last update while rooted ran into a heck of a lot of problems and had to end up doing a SBF in order to get things working correctly again. You should always restore any stock apps and unroot before installing an update. Always.
And yes, unrooting with aRoot is as simple as running the unroot.bat file.
But don't jump to any conclusions about the Gingerbread update being eminent. The article just talks about two users receiving the update. It could be a test run or an accidental leak. We don't know for sure yet. Nothing official has been announced, and it hasn't been anything close to widespread.
