Just thought I would let you all know, that there is an app that temporarily removes root, I work for Sky Sports(attached to Sky), and i've known for a while that it wouldn't work on rooted devices, DRM and all that.
However, some testing i've done with my Galaxy S2, i've found an app which removes root(backs it up too), OTA RootKeeper, it temporaily unroot,(keeps backup) basically allows any apps that dont' work with root to work.
Tested and tried, i'm just hoping the guys at Text and Mobile division at Sky bring out anytime or even anytime+ in the near future.
Though we love our apple products within Sky, so may be a while before android gets anything like that, I on the other hand hate Apple.
Thought I would give people a heads up on how to get the new app working.
