PSP Go isn't even out yet and Sony's already dishing out the feature updates -- PSP firmware 6.10, announced today, allows the slider handheld to tether to your cellphone over Bluetooth for remote internet access. That's actually a pretty handy feature for a system that relies on network game distribution, don't you think? That's not all, however: all PSPs will get a new XMB feature called SensMe which can generate playlists based on "moods," and the PC-based MediaGo software is being updated as well. Not a bad haul -- we'll let you know when it goes live. SensMe video after the break.
