Good here. AT&T. In fact, it feels really snappy. So much so that I've been using up more data than I need to so I had to turn off cellular data so I don't go over.
Another reason to wait to upgrade.
Antenna Gate ....Part 2
This time it's personal ....networks
So glad i decided to wait on upgrading to both iphone 5 and ios6... Terrible issues with both that will take months to fix.
