Xperia blog says the firmware is targeted for users in Middle East North Africa region. It contains minor bug fixes. If you do download, just be aware that you won’t be able to root using the zergRush method. The only way around this is by installing the old 4.0.2.A.0.42 stock kernel for users with locked bootloader
Is there any other workaround for rooting?
