That version is the Middle East PR1.3 variant.

After all the trouble OTA updating has given various people, the best suggestion I can give you is to simply re-flash your phone to the Global PR1.3.

Please use the power search to search the term 'Updating Wiki', click the first result and read it through, then read it again. You only need concern yourself with the section dedicated to the OS you will be flashing the phone from, be it a flavour of Linux, Windows or MAC OS X.

Perform a full backup and transfer it to a PC for safe keeping, before you begin! You can then restore your applications and settings from this backup once you have finished flashing.
