Hello Brian
Sorry to hear that your hopes have been dashed and that the issue has not been resolved. I too thought it had been fixed when my phone updated for 1 hour over AT&T's data network a few days ago. It has since failed to do so at all, except over wifi. All I have is a blank blue page with Orlando, the current time, and "Update Failed" at bottom of screen.
So, here is a rundown on what I have learned.
1. This issue started for me in late November, with my iPhone 4.
2. It does not appear to be specific to ios 6.0.1 or 6.0.2 as some people who are experiencing the issue are running ios 5.x and even 4.x as was the AT&T tech whom I spoke with 2 days ago when his device failed to update.
3. Erasing and restoring the operating system (even without installing data from a backup) does not resolve the issue. Neither does a Hard reset, resetting Network settings, toggling on/off Airplane mode, or reboot after reboot.
4. The issue appears on iPhones 3GS, 4, 4S, and 5 (yes all of them).
5. It does not matter where you go...I travel all over the US...the issue appears everywhere.
6. All other apps on my phone work perfectly using mobile data (4G/LTE)...even location based apps work.
7. There does not seem to be anyone, as far as I have been able to ascertain, who is on the Verizon or Sprint Networks having this issue. If there are, please let us know. My family and friends who are on these 2 Networks are reporting no problems.
8. This problem occurred for users on the Meteor Network in Ireland a couple of years ago, and is now affecting some users on Vodafone in the UK. The problem was resolved with a firmware upgrade by METEOR.

9. My phone was tested at the Apple store against 3 inhouse Test phones. The weather app on all 3 test phones failed to update over the AT&T network, as did the Apple Genius' own personal phone.
10. The common thread here: AT&T.
11. Silence from AT&T.
Yes, the silence is deafening. However, they are literally SHOUTING at all of us "We don't care about customer service!"
I once said that I would never use AT&T again as a service provider. But, I believe in giving second chances for the most part, and I gave them one. That will not happen again, and they can rest assured of that promise.
As in all aspects of life, when you settle for less, ultimately...that is exactly what you get.
All the best,
joe
