hmmm, im also lost now.   anyway are you sure you are not accidently delete it.? by the way other that bro qwe anyone also encountered the same problem at least one people..
use itunes and you can sync into your MBP, and also make sure what thing you want to sync the iphone with the macbook.

p/sL there a way you can take the backup data from your itunes and save it into you new MBP. i think it can sync just like what it has in your old laptop/pc/mac's i think. but im not sure where the backup file, try to google it to fnd the answer.
