New exploit found in iPhone hardware makes it jailbreakable for life

A new exploit discovered in the iPhone hardware, or more specifically, the A4 processor, makes the iPhone, iPod touch 4G and the iPad jailbreakable for life. The exploit is found in the A4 hardware, so Apple can't patch this through a software update without updating the hardware.

The exploit is similar to that of the iPhone 3GS, old bootrom, before Apple released an updated hardware revision to block the exploit. However, this is still a tethered jailbreak, meaning you won't be able to reboot the device without having it connected to your Mac or PC. However, the iPhone hacking community will likely discover a way to package this into an untethered release, so users can keep their jailbreak.

With this type of exploit discovered, Apple may update their hardware on the iPhone 4, iPod touch 4G and iPad to prevent hackers from exploiting the device. This news comes only a day after Apple released iOS 4.1 and iPod touch 4G shipped to customers.

Perhaps the Mexican Carrier executive was right; Apple might be releasing a hardware revision after all.

Steve would just say "We'll just release iPhone5 instead (and quietly fix the antenna) - you people have just given us the perfect excuse"

Ironically enough you might have nailed that one. There is no way they could slip out a "fixed" iPhone 5 with just an antenna fix w/o there being some major uprising but now they can and say its a security thing and they won't take as big a hit. They can push blame off on Samsung, tell people they need this fix and they'll buy more of Steve's kool-aid

People who find these exploits need to be hired by Apple, Microsoft....whoever. Companies cannot discover these exploits on their own but it seems independent people find them out quickly.

I wouldn't be surprised if they sometimes are.

I love it when the community forces apple to fix the antenna.. I hope it gets fixed before march, which is when I'm due for my update...
It's already fixed, all new iPhone 4s that ship September and after don't have the antenna problem (hardware revision).

Current customers were told by AT&T, Apple, and even Steve Jobs himself: if you are unhappy with the phone, then return it for a full refund. A hardware revision due to all the publicity of the issue was predicted by many people. I didn't refund my iPhone because I wasn't effected by the issue. Would I prefer this newer hardware revised iPhone? Sure, I guess. Will I be losing any sleep over it? Nah, my iPhone 4 works just fine.

But can this also be exploited by malware?
If people choose to use it to jailbreak their own phones, that's fine (I personally don't), but I don't want malware using the same exploit to get into my phone uninvited.

Well.. seeing as this is a tethered exploit I doubt that's possible.

Tethered simply means it has to be connected to a computer to function. This doesn't rule out malware on a computer using said exploit to deploy a payload onto your device. This would have ample opportunity to do so as a lot of people sync their devices every day.

Some jailbreaks use holes, others use exploits. Exploit =/= hole. The PDF exploit that Jailbreakme.com used was a bad one that could have made malware a reality on iPhones. This particular hole in the A4 looks like you have to have your iPhone attached to your computer to take advantage of it.

So if there can be an untethered jailbreak, what's to stop untethered malware?
I find this worrying - amid all the excitement over jailbreaking, it's still an exploit => risk.

meh? tethered no thanks, i'll just stick to 4.0.1 and I can't turn my device on/off without worrying that i'll lose my unlock which I need. hdr and gamecenter aren't worth the upgrade
