Sony released the latest ICS firmware update for Xperia P, U, go and Sun (6.1.1.B.1.89)
New update firmware for most of the Sony smartphone market last year, with chipset NovaThor U8500 . Specifically, these are again Xperia P, U, go and Sun that after about two weeks receive a new minor update still based on ICS.
The firmware replaces the last (6.1.1.B.1.75) and most likely will be the last that the manufacturer will release with Android 4.0.4 before making the move to Jelly Bean , for now provided only on the Xperia P and Xperia go .
There were no major changes except the usual bug fixes and increased stability.
