iPad 3 Wi-Fi only IOS 5.1.1 JB freezes whenever I attempt to follow a link from within a reading/news app such as Pulse, Flipboard, Zite, or Trap!t. No error message, just a frozen screen. Can force close app, but closing/restarting app doesn't solve problem. Neither does deleting/reinstalling apps, or rebooting iPad. Can't RE-restore/rejailbreak, because I'm on factory 5.1.1. Any troubleshooting suggestions would be appreciated.
