Just a quick heads-up to let Sony Xperia U owners know that a new firmware version has been certified on the PTCRB website. Firmware version 6.1.1.C.1.10 is interesting as it is the first 6.1.1.C.X.XX version that we have seen i.e. the ‘C’ in the firmware number. Sometimes the change in letter denotes a different region, but we can’t be confident this will be the case here. The last version to be certified was 6.1.1.B.1.54, so maybe this new 6.1.1.C.X.XX version is an update on that. We expect this to be another version of ICS, so don’t go expecting JB just yet.
