It looks like there was some new software that was recently certified by the PTCRB for three of the newest members of the Xperia family – the Xperia P, Xperia U and Xperia sola. Firmware version 6.0.B.3.162 was certified on 15 June and could be heading to these handsets soon.
Recently not all Xperia software versions have been appearing on PTCRB which could mean Sony Mobile is not pushing all software through PTCRB or that they have asked PTCRB not to make them publicly available.
Thanks @tanalibera!
