If people want to tinker (I am away at the moment and have very limited time), I'm posting the OTA Update here. Please
DON'T APPLY THIS IF YOU WANT TO CONTINUE TO RUN THINGS AS ROOT. THIS IS POSTED FOR RESEARCH ONLY. IF YOU COPY THIS TO YOUR SDCARD AND REBOOT INTO RECOVERY IT WILL UNROOT YOUR DEVICE AND THERE IS CURRENTLY NO KNOWN METHOD TO ROOT IT AGAIN!
I will post a safe update.zip at a later point, if you want to get the software updates without updating recovery etc.
