Sony has announced that Vodafone will be the "preferred partner" for the PS Vita's 3G data connection services when it launches in the UK next year. Vodafone sims will be included with the 3G models at retail, though since the handheld isn't locked to a network, you'll almost certainly be able to go with your provider of choice. However, you'll get Wipeout 2048 for free if you buy directly from Vodafone themselves.
The 3G Vita system will set you back £279 (plus memory card, natch). Will you be shelling out the extra money for it?
