Can't sync laptop to iPhone 4S?

Whenever i go to my device then 'summary' where it says what's on the device and how much storage it's got (audio, photos, apps, other) to the bottom right it SHOULD say 'apply' according to everything i've read, but it only says 'sync' and when i press that it just loads then doesn't do anything. I've backed up my phone and it's up to date software wise, so why can't it sync with my laptop? (I'm trying to get music from my laptop to my phone, if that helps)

Under the "Summary" tab, have you selected "Automatically sync when this iPhone is connected"?

You could also select "Sync with this iPhone over Wi-Fi" and see if that works. http://support.apple.com/.../kb/HT1386

Hope this helps.

ITunes is some way a confused program to use, and if you want to sync music from your laptop to iPhone, I guess this article helps you a lot. http://www.imobie.com/...one-5s.htm
