After trying to find a work-around myself and opening a support ticket with Kendo UI (#709522), it seems that Kendo UI is not compatible with Cordova 2.7. This is potentially due to the location.hashchange-related bug
in Cordova.Initializing the Kendo UI Application after deviceready does not seem to fix it either. If anyone comes up with a work-around that works on Android and iOS, I'd love to know about it. Until then, Kendo UI Mobile users seem stuck on Cordova 2.4.
P.S. The new thread page keeps telling me "Invalid post content."
