Bypass the UDID registration on mac and windows 7.
I don’t know if you can do the same on xp or any other version of windows but i’m guessing that just blocking itunes to access the internet during the update process of the iphone to 3.0 will work.
Windows Vista or Windows 7 Users
1.Click on start
2.type in “Search programs and files” firewall.
3.Try to find windows firewall
with Advanced Security if you are in windows 7 otherwise try to get on the advanced settings of windows firewall.
4.Create a new outgoing rule that blocks iTunes.exe from using the internet.
5.Enjoy
This will just stop iTunes from accessing the internet which prevents it from checking if ur UDID is on the Developer List.
After doing that you can unblock it and use itunes with the internet but if you connect your iphone be sure to block itunes access to the internet.
Mac Users
1. Disconnect the internet once you plug in ur iPhone
