You cant change your name or email its for copyrite and security reasons!Matt/HeadShotMatt3
I'm pretty sure neither copyright nor security reasons have anything to do with not being allowed to change our PSN Names.
And you can easily change your e-mail address.
I give it to Sony for allowing to change the email address for our ID's "HASSLE FREE" unlike M$ where it's FLAMING HOOPS to change that. But for a couple $$$ they allow you to change your actual Gamertag. I'm happy with my PSN ID (name) but I would like the ability to change it if I wanted to and KEEP ALL my trophies and game saves associated with it.
