Samsung is dropping an upgraded version of their T9 music phone, dubbed the T9+, that features some additional wireless sharing features. It's got the Zuney song-sharing functions that the last incarnation had, and it ups the ante by allowing wireless games to be played with anyone else with a T9+ within 30 feet. There are already a few multiplayer games made for it, with more on the way. It's all well and good, although I think you'd be hard pressed to find a situation where you're with a group of people where multiple T9+'s will be present.
It's headed to Korea first, with English software updates coming soon to prep for a North American version.
