How can I transfer my blackerry contacts to my new Iphone 5? I cannot find the info tab on my computer. When I go into Itunes I only get the music page.

Can you please help me to transfer my blackerry contacts to my new Iphone? I have tried uploading my blackberry contacts to Blackberry desk manager and tried to connect through to Iphone using Itunes but I cannot locate where the info tab is that I need to go into to sync my contacts? When I launch Itunes I just go directly to the music page. Also I do not see my device. It does sync my device when I plug this in but I cannot actually see the device. Can someone please help as this is stressing me out. Barbara
