I got this today "C0-11136-2 Restore failed" but it's because the game I downloaded from an American account was locked and it wouldn't play on my UK account, they need to allow more than one account per PSV!!
Yea we need more than one account mainly because uk store sucks big time. I'm after quite a few psp games but the ones I want aren't on the store yet
