    I have no idea how to fix that but I just found out the new ios 6.1 came out and i wonder if u lose all ur data to factory settings if you update it?

    Same here. Wifi works fine but in cellular I have full bars on 4G but no traffic. I was having this problem randomly before the update, now not even a hard reset helps at all.

    Have you tried resetting network settings?


    Settings > General > Reset > Reset Network Settings


    Note this will reset all network settings, including passwords, VPN, and APN settings.

    Already tried that, doesn't help. I also tried toggling Settings>General>Cellular>ON, no help there either. I've tried all these things multiple times, all that's left is a full restore. I'll report back in the morning once I restore.

    UPDATE: After resetting Network settings for the fourth time, cellular data began working again momentarily, then quit again and hasn't worked again. Pretty weird.

    I'm having the same problem with my iPhone 5, it started with beta 5 and now even with the official release.

    UPDATE: Ok, I just got back from the Apple store and I've performed a full restore. The good news is that the restore did allow cellular data to work again, restoring as new and restoring an iCloud backup both worked fine. I also tried everything Apple suggests on the http://support.apple.com/kb/TS3780 an only restoring had any effect. Even though that worked for me, I went Ahead and went to the Apple store because this problem had already occurred with me, but only intermittently (requiring frequent resets); the 6.1 update seemed to just make it more 'permanent' so to speak. after the tech tested it with a known-good SIM compared to a new iphone 5, he observed the same stalled cellular data, so my iPhone was swapped out. Hope this helps.

    Ok, I called my carrier customer service, and apparently it is a problem on their side, their system needs to be manually updated in my case to work with the new OS, after that just a reboot and everything is perfect and even the battery is better, with the previous OS which gave me about 8-10 hours with fair usage, the new one almost 14 hours with moderate, slightly-heavy usage and it is actually pretty good.
