The iPhone DeV Team posted an update for Redsn0w 0.9.5 a couple of hours ago which now works with iOS 4 on iPhone 3G and iPod Touch 2G. This will not only jailbreak the device but also hacktivate it.

Redsn0w beta has been updated to hacktivate iOS 4.0 for iPhone3G (in addition to jailbreaking the iPhone3G and iPod Touch 2G). For now, the redsn0w beta release supports only the iPhone3G and iPod Touch 2G at today’s 4.0. It’s still a beta, so you’ll need to let Cydia reorganize, reload, and update after using redsn0w.
