This jailbreak for iOS 7 uses a bootrom exploit to jailbreak your iDevice straight from your iPhone, iPad, or iPod. A bootrom exploit can never be patched by APPLE since the the jailbreak explloits hardware.
No need to download any complicated jailbreaking software. Just google iOS 7 Jailbreak on your iPhone, iPad, or iPod and follow the onscreen instructions. Just click the button on your screen and Cydia will begin to download! (Sorry I can't post the link because it is against the rules of the forum).
I've done it and it works great so far.
