AT&T is supposed to be pushing out an update for the Z10 at midnight tonight, but they have already gone ahead and pushed an update for the Q10 first.
The update is small (only 24MB), but if you're on AT&T, you're going to want to check that Software Update menu and update to the latest OS. The update itself is v10.1.0.2030, but after install your OS versión will be v10.1.0.2121. Notice anything new with this latest update? Let us know in the comments!
