Back When psvita was being marketed and advertised, it was part of the scheme. 3G internet provided exclusively by AT&T... for usa, or least where i live. While i never used that service, i didn't like it was exclusive, cause i had been using t-mobile or something else. So i never use it even though my vita supports it. I dunno about international support for the vita 3G. But has anyone ever used it or does use it? At least tried it at all i am asking. I just like to know, or least explain what features or functions it has.... besides playing online games anywhere.
