Activate your iPhone using .NET 2.0
It appears that Jon Johansen (DVD Jon) is now a .NET developer. He has created a little .NET 2.0 application to activate your iPhone without giving any personal information to AT&T. The application runs as an activation server on your local machine. You then redirect albert.apple.com to 127.0.0.1 in your hosts file. Zac Bowling is attempting to get it working on the Mac via Mono.
