For those that are concerned about the manual zip update...
I did it this morning and my phone is working perfectly.
I simply downloaded the file, changed it to .ZIP and then transferred it to a directory on my external SD card.
You need not have a phone that is rooted. Mine wasn't.
The only downside is that it will wipe your internal phone's drive so be certain to back everything up. I used MY BACKUP PRO. I also backed up my Nova Launcher settings.
Once you are done updating the phone, do a factory reset just to make certain that your phone is fully functioning as it should be.
Really, the update is simple to do and it won't brick your phone.
And listen, I understand there are those that just don't want to reset their phone. But you know what? I got tired of waiting almost 3 days for an update, constantly pushing my clock ahead through 2013 hoping for a lucky opportunity for the update to appear. Now I I hear AT&T has caught on to the time/date change practice. So, you want to keep waiting? That's fine. I wanted the update and it was worth the work to get it, even if meant erasing my phone entirely.
AT&T really sucks when it comes to these updates. Verizon and the other carriers don't put you through all this nonsense.
