    I received my new x200 with AT&T WWAN built in. I have an iPhone 3G with data plan that I want to pop the sim card out of and use in my x200 from time to time. I read that its possible, but I've had no luck so far.

    Any tutorials on how to do this? I go to the Thinkpad mobile broadband connect, and it wants me to sign up.

    I've installed the AT&T communication manager, it sets everything up, i see signal strength, then it results in an ERROR 734 when i click CONNECT.

    Anyone have any suggestions, or an easy step by step tutorial on how to set this up??
