How can I cancel a PSN account?

I wanna create another account coz' in my mexican one I can't do anything on my PSPgo and I can't download games so I'm gonna create an american account but how can I cancel my previous mexican account on my PSPgo and in Media Go?

I don't think its possible to delete a PSN account, but don't take my word for it, here's a site with more details and information in regards to PSN accounts:

I hope this helps answer your question.

on top of the psn store go press triangle on account setting. Then go delete and now ur able to make a new account. make sure to make another email since ur making a new psn account.

that's one thing sony doesnt have.. they dont even have the capability of easily changing your psn id.

Scroll to the Account Management option, press Triangle and select Delete Account.
