WHY WONT MY IPHONE 5 CONNECT TO ITUNES?

MY IPHONE 5 WONT CONNECT TO MY ITUNES, DOESNT EVEN POP UP IN THE SIDE COLUMN HOWEVER IT DOES OPEN IN IPHOTO. MY MAC SOFTWARE WAS UPGRADED TO IOS 10.6.8 YESTERDAY IN THE APPLE RETAIL STORE TO MAKE IT COMPATIBLE WITH MY IPHONE 5 BUT STILL WONT WORK. BEFORE UPGRADING SOFTWARE WHEN PHONE WAS PLUGGED IN I GOT A MESSAGE SAYING THAT I NEEDED SOFTWARE UPDATE BUT NOW THAT SOFTWARE HAS BEEN UPDATED MY PHONE WILL NOT CONNECT AT ALL! I AM CONFUSED.COM! CAN ANYONE SHED SOME LIGHT ON THIS?
