It seems that new owners of Sony’s new handheld are having a few teething problems with the European Preorder incentive codes.
UPDATED: Sony have not de-activated the preorder codes for the time being while they look into this problem.
When users last night attempted to redeem the codes that they were sent via email from Sony, they encountered a error telling them the code was invalid. However, Sony were quick on the case and reported a couple of hours later that the problem had been solved.
However, this does not seem the case now, as upon waking this morning many users have been reporting that the code they got, even though it states the game they chose in the email, handed them the £5/5 Euro discount off of Hustle Kings.
Sony are looking into the issue and we will update with any further information when we get it.
