Correct me if I am wrong, and if I am I will alter my post, you also made at 1 time early on a stand alone GoogleQuickSearchBox.apk? I have it, I use it, I swear I thought you did that. You might have rolled it into full theme, but at 1 time I got it someplace and I could have sworn it was you. Am I wrong?
And when I say OTA I am referring to the .21 OTA update from a few days ago. It will fail with this apk in place.
It might have stemmed from this original thread from you:
http://xdaforums.com/showthread.php?t=1562095 as in it, on page #1 you mention V.X BETA Themed GoogleQuickSearchBox.apk
I am not pointing fingers or pissed or anything, just trying to alert people that IF that had that legacy apk and IF they try to do the .21 OTA update and IF it fails, they need to roll this apk back to the OG file and the OTA will work
