That's incredible!
Using my iPhone 5 iOS 7.0.2 with ubuntu 12.10 64bit by desktop computer I don't have this problem.
Instead, using my iPhone with ubuntu 13.10 32bit by TOSHIBA NB100 I have this problem exactly like in Bug Description.
I'm afraid of install or update 12.10 to 13.10 (on my 64bit desktop computer) because internet by iPhone is my unique possibility to have internet!
