While Sony may have created some excitement in the last seven days with all their IFA announcements, for owners of some of the 2011 Xperia devices on O2 UK there is less cause for celebration.

The British carrier has decided to block the update to Ice Cream Sandwich for three Xperia devices, the Arc, Ray and Neo. Despite Sony themselves having already released the updates for unlocked versions of all three devices, O2 claims that performance issues have caused them to block the update for their customers.

They claim that Android 4.0 affected the devices' speed and performance, and since it didn't meet their requirements, O2 customers with one of these devices will remain on Gingerbread.
