I need to change my Apple ID BUT?

I share my apple id with my sister's ipod from my iphone it is time for my to have my own but will it delete my pictures and apps from eithier phones?!

There's no way around it, unless you have your songs saved as mp3s somewhere on your computer. Once you make your own itunes, open it, Click file and import song from file, highlight all the songs in the folder that has your music (probably the my music file) and press enter. If you bought all your *** through iTunes, I'm sorry but you are beat.

Switching to a new apple id won't delete the apps per se, but if it's time for those apps to be updated iTunes will require you to login with the previous apple id. This can become a hassle. I recommend downloading all the free apps under your new apple id and downloading the paid apps under the apple id you share. As for your pictures, I recommend emailing the pictures to yourself, or upload them to your computer and drop them in a shared folder. There are many ways to retrieve your pictures.
