Someone has released a jailbreak for one of the betas of the iPhone 3.0 firmware.  The iPhone dev team, who are responsible for the 3G unlock released a few months ago, hurried to get a post up explaining why they weren’t the ones to release  this latest exploit. Â
They offer proof that they had a jailbreak a few weeks ago, but they kept it to themselves because they’d rather work towards a carrier unlock of 3.0, than try to keep up with a stream of beta releases from Apple.
Before you decide you want to be all cutting edge, a few things to keep in mind before trying to install one of the 3.0 betas, much less jailbreak it.
- The new firmware doesn’t work with the baseband 02.28 firmware unlocked by yellowsn0w.
- Apple is just going to release a new version.
- You may render it impossible to ever unlock your iPhone 3G
- You may not be able to roll back to the released firmware
- Its a knock off of the hard work of the iPhone dev team.
