I got to set it up for her and everything, nice sister she is. Anyways, she has lots of pictures,videos,apps, and contacts on her iPhone 3GS, will it erase everything on the phone if I sync it to her computter? I've read things here and there that it will. I want to sync what's on her phone to her iTunes and new laptop, not sync the empty laptop to the phone and erase all. If you could just fill me in, thanks.
