iTouch won't connect to wifi after updated to iOS 6.1.3
I just updated my iTouch 4 from iOS 5 to 6 and now it won't let me connect to my wifi. We've reset the router and motem and called our service company many times, but that doesn't seem to be the problem because the other devices in the house are still connected to wifi (they still have iOS 5). My friend has the same problem with her iTouch when she comes over-- it won't let her connect.
iPod touch (4th generation), iOS 6.1.3, Updated from iOS 5.1.1
