Within 24 hours of the iOS 4.0 release, Hackers are reacting in wild and update their previous tools to jailbreak iOS 4.0. redsn0w is a popular jailbreaking tool and redsn0w 0.9.5 beta was the first one to jailbreak iPhone OS 4.0 beta which is now called iOS 4.0. MuscleNerd of iPhone Dev Team, has just briefed about the redsn0w 0.9.5 beta update which can jailbreak iOS 4.0 as well.
This means the vulnerabilities discovered in iPhone 4.0 firmware exist in iOS 4.0 GM as well because it is a mere rename. The process to jailbreak iOS 4.0 with redsn0w 0.9.5 is simpler. To execute jailbreak iOS 4.0 on iPhone 3G
- iPhone 3G must have already be updated to earlier iPhone 4.0 beta4 and activated.
- Now update iPhone 3G to iOS 4.0 GM and activate it throuhg iTunes 9.2.
- After that you have to point redsn0w 0.9.5 to previous iPhone 4.0 beta4 firmware.
- This trick will jailbreak your iOS 4.0 GM running on iPhone 3G.
Here are the official instructions which describes how to jailbreak iOS 4.0 on iPhone 3G.
For those who can legitimately activate to the iPhone3G 4.0GM seed, the “point to previous IPSW” redsn0w trick works and will jailbreak your 4.0GM. The “trick” is to point redsn0w at the 4.0beta4 IPSW instead of 4.0GM (do this after you’ve updated to 4.0GM and activated through the new iTunes 9.2). Since the carrier unlocks aren’t yet supported at 4.0, don’t do this if you use yellowsn0w/ultrasn0w/blacksn0w.
