IT:AD:Sencha Touch:Issues
Summary
Sencha, in PhoneGap, on iOS = a lot of spare parts flying in close formation = a lot of potential problems.
Scenario
Has worked in desktop, emulator, and then when deployed to iOS device proper fails.
Solution
Check the case of the html includes (and *.jb3): whereas the emulator lets it slide, the iOS doesn't. The paths are case sensitive.
