Okay..... 24 hours later with me at my iPhone. Last night I was pairing it up with my car stereo so I can use the hands free. The only thing that I find a little annoying is that there is no direct button for bluetooth. Instead, I got to SETTINGS --> GENERAL --> BLUETOOTH. However with the bigger icons, I can do this a lot faster than was I can do it on a windows mobile.
And the other thing that I do like it that iPhone will give you a notification for when the device is paired. Unlike windows mobile with doesn't, and it's not until you try making / receiving a phone call while driving that you find out that your device is not paired at all.
