Redsn0w beta has been updated to hacktivate iOS 4.0 for iPhone3G!

iPhone Dev Team has announced that the redsn0w beta has been updated to hacktivate iOS 4.0 for iPhone3G. This is in addition to jailbreaking iPhone3G and Jailbreaking iPod Touch 2G).
The download links for redsn0w are:

Mac OSX (x86) []
Windows []
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.

The Dev Team also had following updated regarding the same post;

Update #2: There’s a new redsn0w beta (links were changed above) that should fix any iBooks problems people were seeing. Just run this new version 0.9.5b5-4 and deselect Cydia (you don’t want to reinstall Cydia over itself).

Update #3: Remember, there are scammers everywhere in the iPhone scene. The latest one involves something called “ClawPack”. Avoid this costly, untested, and certainly unendorsed ripoff of our free software.

Update #4: There’s a new redsn0w beta (links were changed above) that should fix any APN or MMS issues that users were seeing. It’s safe to re-run it on an already jailbroken iPhone without restoring…just deselect “Install Cydia” if you do that.
