I was actually surprised and excited to see this update this morning but thought it would be ICS.
Long ago I rooted my phone just for gaining control and removing bloatware but ended up flashing my first rom with WildStang's Gingerbread OTA. After that I applied the "Warm" theme and been happy with that thinking there would be no more updates to this phone.
To the point - my question for you all is what do you mean by flash over? When the OTA is pushed is it just a patch or do they somehow send and entire install which removes the previous version, saves your data, installs the new version, and puts back your data? I don't have a problem with wiping and starting fresh, and it sounds like that is what everyone is recommending, I'm just trying to understand how it would even work flashing "over" my current version.
