I am selling my jailbrakeme.com jailbroken iPhone 3G after upgrading to iPhone 4. I went to settings>general>erase all content and settings and after an hour my phone was bricked! It would not get past the apple screen when booting. Luckly I've done jailbreaks before and was able to throw it into DFU mode and restore. Now everything is working fine. Bottome line if your gonna erase all settings you should probabally do a 'start as new iPhone' restore first. I'm probabally gonna get flamed for this thread, but I didn't know so others might not know also. Especially since the new JB is so easy.
