Okay, so I got home and updated my original iPhone to 3.0 beta 2 and got the error again (1611) and so I decided to just do a restore to 3.0b2 and that worked but, I got the purple screen with "Slide for Emergency". Then for some strange reason, I inserted my 3G sim card, and it activated right away. It's never been able to use my 3G card before to activate... that was weird. I checked the AT&T site and it still says I have the regular $30 3G plan and everything. Anyways... it's working now... I have no idea how, but it is.
