I just recently purchased an Alienware laptop, and it has Microsoft MapPoint 2009 on it. I would really want to use this, but it's a lot better with a GPS receiver. Since I'm already using my iPhone 3G as an internet connection, I was wondering if there's any way to use my iPhone as a GPS receiver. I'm willing to jailbreak my iPhone, and i would preferably like it to connect through Bluetooth, but USB is OK. Thanks in advance.
