Earlier today, Sony mistakenly updated the Sony Xperia Z support page with details of the Android 4.3 Jelly Bean build, confirming it will come with firmware version number 10.4.B.0.569. Interestingly, it also pegged the release date as Thursday 19 December i.e. just two days away. The date may be a mistake, but either way, it gives us a date to target. Sony has since changed the support page back to the previous details.
