Today is the launch date for Sony's PSP Go. The new system appears to finally be getting mobile Internet, with a catch. Firmware 6.10, the launch version for the Go will allow users to tether it with a mobile phone using Bluetooth in order to access Internet when away from Wifi hotspots. Of course this does come with a catch. Namely that Bluetooth 2.0 is only about 1/5 as fast as the PSP's 802.11b wifi, meaning downloading games will be painfully slow. You'll also require a costly mobile broadband plan, preferably with unlimited transfer. Older PSPs also cannot use the features and there is no word if USB tethering will be enabled.

Other updates include a redesign of Sony's proprietary Media Go software, which works like iTunes for Sony products. This is linked with the new SensMe feature available for the PSP's audio playback, which selects tracks automatically depending on the preset mood you select. This is vary similar to Apple's Genius.
