I have been using my 8330 curve for nearly two months now with little to no problem. Last night, though, I noticed my ubertwitter hadn't picked up any tweets in the last few hours. Browser and Opera Mini both connected to the internet just fine, so I assumed it was an ubertwitter issue and went to bed.
This morning, I woke up with no connection to bbm, ubertwitter, browser, or opera mini. After doing several resets, Opera Mini will now connect to the internet but nothing else will.
Phone calls, Text messages, and all the usual phone stuff still work fine, its only internet-related things that are not working.
