What happens when you back up your iPhone to a macbook?

I have an iphone5 but I'll be disowning it soon, its a long story.anyways, i of course want to save everything on the iPhone… Pictures, most importantly. So if i back up my iPhone on iTunes (with the computer, not iCloud) will it save everything including all the pictures? I'll be getting the iphone5s when it comes out and was also wondering if i restore the iPhone… Will all my pictures go to that new phone? Because thats what I'm hoping for…

If you have a MacBook, just connect your iPhone to iPhoto and save all your pictures there. Backing up a iPhone to iTunes saves everything like apps, songs, movies, settings, ect.

Matthew was right. Honestly, it really is not a very good idea to use your phone to store your photos. You should always transfer them to your computer if they are photos you want to keep, regardless of if you want to get a new phone or not.

And don't hold your breath waiting for the iPhone 5s. It is not being released on Sept. 10th. The new phones are just going to be officially announced on the 10th. They will be out 2 or 3 months after iOS 7 is finally launched
