Most convenient method to switch between PSN accounts to access PS Vita content from different Playstation Stores?

Question

I have a Japanese PSN account, as well as a US PSN account. On my PS3, I get the best of both world since I have access to Japanese Playstation Store as well as US Playstation Store. I can purchase and download new region specific demos and games, and use them from my both accounts.

I want to do the same on my PS Vita. However, it seems we do not have that much freedom on PS Vita. First of all, I cannot add a second Playstation account on PS Vita, therefore I cannot directly access a second store. I tried to download contents on my PS3 first, and then to send it to my PS3 : I obtained an error message telling me I could not do this because my PS3 Vita account was not the owner of that content.

I think there are two methods to get content from both Playstation Stores : - 1 : format my PS Vita and recreate the account info (as well as network connections info, etc) for the other region every time I want to use content from a different region - 2 : buy a new PS Vita Memory Card and save my alternate account information on this card, then save region specific content on this card. When I want to switch region, I then need to change the small memory card (so small.. hope I won't break it.. Or lose it) Am I correct ? Are there any restrictions or problems with these methods ? Is there a more clever or convenient way of switching between accounts ?

Thanks for any suggestion !

Answer 1

You can have two different memory cards, one for each user, but you will need to do a factory reset each time you swtich your memory cards, see the following video, courtesy of IGN:

Answer 2

Do a backup of each different region PSN account you login to a PC. Then if you want to switch, just load that specific save file. No need hastle of restoring factory settings or buying another memory card / Vita etc.

Only down side is that you must have access to a PC to switch ...
