Yep, you read it right… Seems like there’s a ROM jailbreak for iPhone…
So anyway, because the newest iOS 4.x have is virtually unjailbreakable, some groups shifted from Software to Hardware and BOOM! Rom hack to jailbreak it!
To make it short, greenpois0n’s jailbreak only works on iPhone 4, while limera1n works on iPhone 3GS\4, iPad and iPod Touch 3G\4.
Jailbreaking the ROM!? Seriously!?
