iPhone OS 4.0 Jailbreak Released

The iPhone Dev-Team has released the first public beta of iPhone OS 4.0 jailbreak tool "RedSn0w 0.9.5" which successfully jailbreaks OS 4.0.

However, there's a catch - this version of RedSn0w (RedSn0w 0.9.5) is only meant for developers of the jailbroken apps so they can test and update the apps before OS 4.0 is released to the masses.

MuscleNerd from the iPhone Dev Team made this announcement via Twitter:

1st public 4.0b1 jailbreak .. Only JB devs til they fix their SW! iPhone3G+Mac only til more is working

iPhone Dev Team has explained the reason for releasing the jailbreak only for jailbreak app developers:

Please not that this beta is not meant for the average end-user. There are many things “broken” with jailbroken apps in the 4.0beta1 environment right now (that's the real reason we showed “Veency” in the 4.0 jailbreak demo video last week, instead of say MobileTerminal.app, which is broken!). This beta redsn0w allows the developers behind those jailbroken apps (like MobileTerminal.app!) to fix their software before the general public gets iphoneOS 4.0.

Because it's meant for JB app developers, this beta redsn0w does not perform hactivation. You'll need a properly-registered developer UDID with Apple to get past the activation screen. For similar reasons, there is no Windows version of this beta redsn0w (since apps are developed on MacOSX).

NOTE:

This Jailbreak is for Developers ONLY

This RedSn0w 0.9.5 BETA release supports:

• iPhone 3G only (for now)
• Mac OSX only (for now)
• the 4.0beta1 Firmware only (for now)

IF YOU RELY ON CARRIER UNLOCK STAY CLEAR OF THIS BETA SOFTWARE

That’s because the beta redsn0w works only if your device has already been upgraded to the stock 4.0beta1 IPSW from Apple, which contains a baseband update. If you installed that OS 4.0 IPSW, and you’ve already lost the carrier unlock you will have to wait till the next planned release of ultrasn0w and blacksn0w becomes available.

How To Use RedSn0w?

1. Updated your iPhone3G to iPhone1,2_4.0_8A230m_Restore.ipsw
2. Launch the beta redsn0w 0.9.5
3. Select your stock iPhone1,2_4.0_8A230m_Restore.ipsw file (you’ve already used this to update your iPhone3G to 4.0beta1)
4. Select “Install Cydia” and click “Next”. Use DFU mode to install the jailbreak.

“When your iPhone3G comes back up, you’ll notice Cydia has a blank white icon (we told you many things were broken right now!) You’ll also notice Cydia has no sources. Go to the Sources panel and add this repo: apt.saurik.com/cydia-3.7 (ignore all network related errors). When Cydia restarts, you should see its real logo now, and the standard sources should be ready to use.” read more
