So I am selling both my iphone and my laptop and was wondering if there is way to copy/save the synced data (texts, notes, phone numbers, etc) so that I can sync my new phone when I buy it? Is there a file/folder I can copy on my computer? Thanks for any help

Is it jailbroken? If so, use ssh and go to /root/var/bin
Most of the phone's files are in here, if not, it's in one of the many other directories, it will be pretty self explanatory once you see the folders. If the phones not jail broken then you're out of luck.

Read this article which describes where the backups of the iPhone synced data are stored.
iPhone and iPod touch: About backups

Not everything is backed up in the backup location mentioned above. Music , video and apps you have synced to the iPhone are not backed up so you need to transfer these to your new computer using another method.

This article talks about using an iPod to move your iTunes media files to a new computer, but any external USB or firewire disk that is large enough could be used as the transfer disk.
