By right there is no ps vita in malaysia yet. Sony has yet to officially launch it here. The one you buy at stores are most probably taiwan or japan unit.

The other thing about the vita is that you can only bind 1 ps network account with it. Which means, if you use your malaysian ps network account, it would be useless, because the ps vita store ia still not avalible here in malaysia.

If you use a us or uk account, you wout be able to bind your credit card or debit card tobit becauee of sonys stupid regional restrictions!

I have a vita and i am using a uk account to buy games =(
