I used QuickPwn to JB my 3G on my Mac and it worked great (even kept all my old files and settings) but when I tried to sync it against my Windows laptop (that it was normally synced with) it just kept rebooting. iTunes 8 on both sides.
I'm doing a normal restore now; I guess I'll wait a day or two for updates before trying again.
Edited to add: I tried again using a custom firmware built with PwnageTool and tried to restore using iTunes on Windows but it gave me Error 6 and failed.
