iPhone 3GS untethered bootrom exploit released

Today saw the release of a new bootrom exploit for the iPhone 3GS, an unpatchable vulnerability which gives jailbreakers total control of this device forever.

Although the iPhone 3GS is now very much a legacy device and few users will be actively using them, the rarity of a bootrom exploit makes it worthy of note. There have been no publicly released exploits of this kind since limera1n, which supported only up to the iPhone 4.
