With a little over a month until the launch of PlayStation Vita, Sony and AT&T have finally nailed down the gaming machine’s 3G data plans.

Two plans will be offered to consumers: 250MB of data for $15 per month, or 2GB for $25 a month, Sony said Monday at the Consumer Electronics Show in Las Vegas. There will be no contracts.

AT&T will handle 3G connectivity for the powerful portable system, which Sony will release in the United States on Feb. 22. You’ll be able to buy the 3G Vita for $300; a Wi-Fi-only version will cost $250.

Chris says: “No contracts?” Hell, there should be a contract: They should give you a Vita for $99.99 if you sign up for two years of 3G.
