It's a weird edge case: Work blocks the HAMB but has wireless. If I forget to turn off wireless before I launch the iPhone app I get a network error box then a blank white screen. Newer iPhones run apps in the background too so when I exit the app and go back I still see the white screen. So I have to reboot to get back in. Can you make it so that the "no network" error exits the app & doesn't leave it hanging.
