If anyone really wants to play online with their Vita (or 3DS or any other wifi enabled device) the only REAL option is to buy a smartphone that is 4G (preferably real 4G, i.e. LTE, like my Galaxy Nexus) and utilize the wifi hotspot features.
That will enable to get FULL net access for your device anywhere at anytime. (obviously limited by your carriers range).
Then the only thing you may have to worry about is your data limits.
Save the extra $50, buy a wifi model, and just get the right phone with associated plans. You're paying the same extra fees (unless you root and rom said device) as the 3G model, but you'll actually get full functionality. Especially if you get a 4G LTE phone.
This is why I laughed at Sony for even offering a 3G model. Its so gimped and really a useless option. I don't see ANY reason for anyone to buy that model... unless they really are ignorant when it comes to available mobile technology and carrier offerings.
