For those who own a Sony Xperia device powered by a ST-Ericsson NovaThor chipset, it looks like a new firmware version will be heading your way soon. A new firmware version 6.1.1.B.1.54 was certified by the PTCRB earlier today.
The firmware has been certified for the four Sony Xperia devices with the NovaThor U8500 chipset which includes the Xperia go, Xperia P, Xperia sola and Xperia U. The update most likely offers only a minor improvement over the existing firmware (6.1.1.B.1.10). We’ll bring you more news if/when it rolls out.
