iPod wont merge contacts from my MacBook through iOS5.

I updated my iOS5 and the iCloud is pretty cool. Only there are two problems..

1: Its iCloud Backup isn't functioning. I get a message saying "There was a problem with iCloud Backup".
2: It isn't merging contacts that are on my Macbook to my iPod (4th Gen). Why so?

 

Ok, my backup worked. It just needs you to connect your iPod/iPhone to a power source. Try turning the wifi off and on, and it should work. This is my experience. It backed up my data like Evernote, Twitter, Mac|Life magazine, Photos.. And for the contacts, I just read online that they will get synced with iTunes. So I will try that!
