Seems to be incorrect on a few points. You can import a Hong Kong model and use it on AT&T or T-Mobile in the states since it’s unlocked. The Japanese model is locked to Docomo, and the American model is locked to AT&T. Based on that, the only model that you could travel abroad with is the Hong Kong Vita unless they unlock the other regions’ units.

- Nope, they specifically said at CES that they aren’t targeting the App Store or Android Market and are only focusing on the core apps (Skype, Flickr, Netflix, Facebook, etc.).
