The new 1.80 firmware update for the PlayStation Vita brings a lot of features to the table, but it also locks a single PSN account to a memory card.
If you want to avoid formatting your memory card every time you access downloadable games from different regions by using multiple accounts you will have to purchase a new memory card.
This could prove annoying for Vita owners, but if you don’t mind owning multiple memory cards there is no real hassle.
Reminds me of the PSone days actually…
