Sony’s released a new Firmware update for PlayStation Vita units in Japan.
We have checked for the update on our unit and it indeed there, although it isn’t obvious what the update is actually for.
According to Andriasang, many users are claiming it seems to be a fix for Japanese 3G systems which have been unable to recognise SIM cards.
The PS Vita is released in Europe on February 22. You can pre-order the Wi-FI version here and the 3G version here.
