Sony pushed live firmware update 3.36 for PlayStation Vita, which is a mandatory download (124MB) if you wish to use PlayStation Network features.
Sony’s comment on the update is that:
Operations quality during use of some applications has been improved.
As a reminder, there will be some PSN maintenance tomorrow, January 15, with a PlayStation Store sale in North America this week discounting a variety of PS Vita and PSP games, as well as PSOne Classics.
