3g iPhone Activation Tips

After waiting in line this morning to pick up two new 3g iPhones, I've begun my review process and will hopefully get a video out tonight. Before I do, I wanted to pass on a tip I noticed, if you are having trouble activating your new 3g iPhone, try activating the phone from a Mac. I'm not sure why it works better, but after trying unsuccessfully for an hour or two, I switched over to a Mac and it activated on the first try.
