Zynga has released a new iPhone game called Scramble Live, and while the game itself isn't anything really new -- it's Boggle, basically -- the technology is pretty interesting. They've already got a Facebook version up and running with over a million users, and the new app will let you play against other users, on both the iPhone and Facebook, in real-time. That's a pretty impressive hook -- rather than building up a new social audience, you can just carry away your Facebook friends and play with them while you're on the iPhone.
Unfortunately, there's a catch (isn't there always?) -- the game's iTunes page says the live game is only available over 3G or Wifi, so us first-gen iPhone users are out of luck for that mode. But there's also a solo mode, as well as a "pass and play" version that you can use to play with people around you.
The game's "on sale" at $2.99 until March 9th, when it'll jump back up to $4.99. If you're a fan of the Facebook version and want to try out some cross-platform gameplay, give it a look.
