Why after the new 5.1 update when the iPhone locks and sleeps the wifi goes what appears to be off and it 3G comes on?
After the new update 5.1 whenever the iPhone locks and sleeps it changes from wifi to 3G. Before the update whenever even in the lock screen the wifi bars were strong and seemed as if it's working even when the phones asleep. Now with the new 5.1 update in lock screen after the phones been asleep for a minute or two it shows 3G then like after 5 seconds or so the wifi comes on.
