I sold my 4GB to my little brother which was already unlocked and jailbroken. I had erased my phone numbers manually. How do i change my email address and password so if he wants to purchase an app or song off the itunes or app store on the phone so the box does not come up with my email address and asking for my password. How do I erase my email and password so he can purchase items in his itunes email and password?

I think you have to reset some settings in the Settings app.
Something like Settings -> General -> Reset.
I don't remember specifically where it is though..

it's either that .. or reinstall the firmware

you just need to sync your iPhone with a different account, therefore, in iTunes, sign in with his account, sync the iPhone and it should work fine.

i jailbroke a friends ipod, and at the time appstore was asking for my account p/w etc, so i think he just sync'd his with his iTunes and his account and it worked fine!

Is it possible to change my password for itunes? or Will my email address continue to show up still asking for my new password?
UPDATE-I signed into my iTunes account and edit my email address and password before i plugged my iphone into the laptop. I tried to purchase a free app and my old email and password address came on the iphone screen, so I plugged in my iPhone into itunes and it automatically updated my new email and password, so my brother will have to plug into his mac's itunes to sync and it should work with his email and password.

You didn't need to erase everything manually. You could have reset. That way it would have been a new phone and your brother could have done everything easily from the beginning.
