I cant believe I haven't seen this story sooner. This morning I got around to going into an Apple store and buying a 3G iPhone. I started asking the sales person about their handheld devices they use to run everything in the store. They use these to track you as a customer, your transactions, take your payment, email you a receipt etc etc
I pressed him for information about the device, who made it, etc etc... He kind of nervously laughed and said "Yeah its not an iPhone, its a Windows Mobile Device" and showed me the back of the device with the Windows Mobile Logo on it. I laughed out loud.
