How do I change my login email address on my ipad 2 itself?

[GAMESHARQ]

In itunes on my PC, I changed my email address, but when I try to log into the appstore on my ipad 2, it still shows the old email address, and when I try to log in, it tells me my password is wrong.

I know the password is right, so the problem seems to be because it's still showing my old email address.

Does anyone know how to change it on my ipad 2 directly?

You would need to change the default account on your iPad. Go to the Settings app, then select "Mail, Contacts, Calendars" and scroll down to where it says "Default account". When you change it, that email account will be the one your iPad will use until you change it again.
