I forgot my itunes username but i know the password. what can i do

Do you mean the password for your iPod or your apple account? If it's your apple account you can go through apple's website and retrieve your username and/or reset your password
My Apple ID

If it's your iPod password you forgot, then unfortunately you will need to reset your device and delete everything on it to get it working again. Here's a link to do just that:
How to Reset Forgotten Password on iPod touch

On the Facebook sign-in page, click the "Forgot your password?" link just below the password box. As long as you know your email, phone, or full name, you'll be able to get your username.

To have an iphone you had to have had an itunes account. There's no way around that.

You can go to their forgot password and reset it and see what it was. Or you can just open a new free account through them.

With out an itunes account, you can't update now, you can't download apps or anything.

Hi mariamy,
You will have to open up iTunes on your computer to reset your password. Once you have iTunes open, click on iTunes Store on the left column. Then, click on your iTunes username in the upper right hand corner. A window should then pop up, with a "Forgot Password" button. This will open up your default web browser. Follow the instructions from there and you should be all set!
Hope this helps!

there should be a button that says forgot password/username when you go to log in you need the email you used when you made the account

go to a PC/computer/laptop and go to iTunes.com. Click on forgot login or whatever. type in your secret information, and check your email for confirmation.

Click the iTunes Store link on the left side of iTunes. Then click your username in the nav bar, just under the search text box and when it asks you to log in, click "forgot password". Follow the on screen instructions from there and you should be golden. Good luck!
