I try to sync my contacts on my iphone 4 or 4s and when I connect the iphone to my MacBook OSX (version 10.6.8), the iphone device only opens up in iphoto not itunes. It's not showing up in itunes. thus, I cannot sync all my contacts to my address book on MacBook. I'm older than most of you reading this post, so please help with any advice. Thanks so much!!
