iPhone - the first day was very frustrating
I bought an iPhone on Friday (6/29). Over the weekend, I tried to activate it with an exiting SIM from my employer. I was stuck on the first screen as it demanded the last 4 digits of the SSN of the owner of the existing number. I tried hard to get the device to work without AT&T service. I could not pull it off. I have since found some other frustrated customers (Om Malik). He does refer to some potential workarounds in his post.

Right now, I feel worse about AT&T / Apple gang than I ever felt about the Wintel crowd. I cannot understand why WiFi, Camera, iPod had to be disabled if I did not have cellular service.
