Yes! Although my phone says I have full 4G, and nothing using internet will work at all. Is this what you're experiencing? It's also good to note that I just updated to JB manually.
I updated yesterday and data was working fine up until an hour ago. WiFi works fine but my phone will show 3g or 4g coverage but no Internet connection. I think it's a Verizon issue, not the update.
Oh, that makes me feel so much better. I wasn't sure if I should factory reset. Thanks for sharing the issue, hopefully we'll see if other people have it too.
Ah good... sorta, lol... been trying to figure out why the *&!@^ we can't get internet today on our phones. Sigh, tried everything... finally searched... and found this thread
