My client's iPhone 4S (still on iOS5 -- did not touch iOS 6 yet)'s Internet stopped working since e-mails, Maps, etc. don't download. We tried powering it off and on to reboot, but that did not help. The voice phone part works though. This is on Verizon Wireless' carrier with is 3G data. Wifi works fine. Also, it says it needs an upgrade? Is that iOS 6? Is there an outage or is there something wrong with the iPhone? Is Verizon Wireless having problems?
