Hi..i just got my ps vita...but i am having trouble updating it using my ps3 system..btw i don't have wifi modem to connect my vita..

y must come to your house meh?

I heard ps vita can only use one psn account? Can't switch psn like ps3 ... is that true?

I wanna ask something about my Vita..

I have a demo downloaded on background and then everytime I run Ninja Gaiden Sigma Plus, the notifications popped up and say the networks features have been disabled, thus stopping my downloaded demo on background...

The only way I can continue is to touch again the downloaded title from the bubbles..but when resuming the game, same notification appeared again...

Does it mean I cannot download anything when the game is running or something else..? Do I get signed out from PS Network as well...?

i wanna buy ps vita today!!! but 3g not yet out from sony centre@sony style
