Here's what's going on. I had my old iPhone 3g synced to my desktop computer. I then bought the new iphone 4g and had it sync with my laptop. I now need my 4g to sync with the desktop so I can get all my contacts off the 3g. Whenever I connect my 4g to the desktop the Devices menu shows the 4g but all it says is "iPhone" in the middle of the screen. How do I get the 4g to sync with the desktop and transfer all my contacts over?
