New Mac.. iPhone backup?

[MatDave]

Hi,

I am selling my MacBook Pro for a MacBook Air. So I will make sure to keep all my files somewhere so I can push it all back into my new mac, but I have a problem : the iPhone, the iPad.
I don't see their backups showing up in the finder.

I'm afraid when I plug my iphone into the new mac, it will open iTunes and say it is already synced with another library, would you like to erase it all and sync it with this new one?
So I'm gonna loose my backup at that point or something?

Or it will be aaaalll good, and will create backup in the new mac with how my iphone is at the moment i plug it in, i mean, all the settings, messages etc etc

THANKS IF SOMEBODY CAN HELP, I'M ANXIOUS

The following gives information on where the backup is stored: http://support.apple.com/kb/HT4946 Note that the files may be hidden. One way to see them is to open Finder, go to the "Go" menu at the top of the screen and click on it and then hold down the Option key.
