1. Is the PSP Go region free
2. Are PSN games region free?
and the final question is that I live in Australia, and I setup a PSN account for the US, then I chose a game that you cannot get on the Australian PS Store (Final Fantasy Tactics) clicked buy now then asked about my credit card, but it wanted my address and state, but it wouldn't let me change countries, so it said that the information didn't match my credit card, how can I but a US PSN game on my current country
BTW I didn't mention but I was using Media Go on Windows Se7en
The first idea that comes to mind is the prepaid cards.
Google for Playstation Network Card, I think they have them in $20us increments. If you can find a way to get your hands on a few, you can add funds to your account. No idea if the games or system are region free though.
Every time you want to change to your US account, your have to deactivate your Australian account, then delete the account from your PSP. Then, log in using your American account and activate your PSP with that account. To change back, do the opposite. Alternately, if you install a game using a PS3, it will automatically deactivate and then activate the PSP to the account from which the game was purchased.
It's kind of a pain in the a-hole but there are no other choices if you want to use multiple accounts.
As for buying games on the US store, try maximuscards.com. As long as you have access to paypal they will hook you up.
bah! that's darn evil that $ony would not let you keep your data from multiple regions on there, so you could bring it up no matter where you live. Sounds like they want ppl to buy 2 systems.
