So, idk if this has already been discussed but my iPhone 5 was having problems automatically connecting to wifi networks and once connected to a wifi network, it would only stay connected for a limited time. A week or two ago I went to the Apple Store in Raleigh, NC and they told me it is a known issue. The guy I talked to said its a software AND firmware problem. He said he does not have a timeline on when Apple is going to fix this and that as of now, Verizon will still charge me for going over my 2GB plan. He told me a somewhat temporary fix is to go into wifi settings and click on the wifi network you use often and switch the HTTP proxy to "Auto" Hope this helps!
