This leaked Sony Ericsson's F305 phone is notable for a couple reasons. One, it's their first motion gaming phone under the F-line (there've been one or two here and there for various other phones), which makes us and The Unofficial Sony Ericsson Blog think that it the series stands for "Fun". Two, it's got PlayStation buttons on there, namely the O and the X, giving users an NES-level of complexity to the games.
Other details are slightly less impressive. It's quad-band GSM with only EDGE, has a Power Pack CCP-100 purchasable accessory for backup battery capabilities, stereo rear speakers, Bluetooth connectivity to other phones for multiplayer, Memory Stick Micro slot, built-in FM, TrackID track recognition, and a "selected market" release in Q3 of this year. Se-nse says it'll be formally announced on Tuesday. [Se-nse]
