To my understanding, this low level bootrom exploit means that all the iOS devices currently released will always be jailbreak-able, right?
But here is where I am confused, for example, I jailbreak my iPhone 4 on 4.1 firmware with the SHAtter exploit, and Apple releases 4.2, this means I can update and just re-jailbreak? Or would I have to wait for a new jailbreak software to be released? Or is this just simply meaning that jailbreaking newer firmware will be easy, or a snap, and will not be patched until new hardware has been revised?
If you can, explain EVERY little detail on this exploit and how it will work. I don't know too much about this whole 'low level bootrom exploit'.

If this is an iboot exploit, you could probably restore to Custom firmware and be already jailbroken when successfully restored.,

SHAtter is in the bootrom exploit family, but SHAtter by itself is likely not enough to produce an untethered jailbreak of an iPhone 4, for instance.
For every bootrom exploit, you'll need an iBoot exploit as well to flash the exploited code to the NOR on SHSH blob-required devices and to load in an unsigned kernel. Though we have (had) those exploits, Apple releases new firmware (complete with new blobs) to seal holes in iBoot. Meaning new devices and new firmwares need new iBoot exploits to make the bootrom exploit work at all/work untethered (OR you have a old, exploitable iBoot with the blobs for your device to match).

I get it now. Same exploit means easier jailbreak because they don't have to find another. Thank you!

hey guys thanks for the info.. a little confused tho. maybe someone can clearify for me.. when shatter comes out and i jailbreak my 4.1 iphone 4 if i restore for any reason after and try to bring it to apple to say be fixed or whatever will the restore wipe the info? or will apple be able to tell? thanks everyone! sorry if this was answered already.. i did not see it anywhere.....

I have never heard of apple finding out after a factory restore, and have returned/ had replaced many of iPhone that were previously jailbroken with zero problems.

Also, Brokencydez, that's not entirely right. Jailbreaks are almost always a combination of exploits. blackra1n is a combination of the usb_control_msg(0x21,2) for iBoot and 0x2400 Segment Overflow in the VROM exploits (and redsn0w uses this same attack route for 3.1.2), Spirit uses three exploits (sneaky dots in backup restores, incomplete code signing, and the BPF_STX kernel stack overwrite).
We've got the bootrom (I actually now think SHAtter isn't a "bootrom" exploit, but is elsewhere in the hardware and is therefore unfixable like a bootrom exploit, allowing unsigned code over USB) one down, but the iBoot hole needed to launch/flash unsigned code is still, and will be, needed in the future as long as SHSH blobs are enforced in the capacity Apple designed them to be.

The new JB is tethered? Thats me fooked then. I live in the uk but have an iphone I bought in the US wshich was locked to at&t. If I update it, I will lose my unlock as well as being able to tether it to my pc. Will there be a work around solution OR am I screwed bigtime?? Thanks guys

If the past jailbreaks are indicative of the future BigCol, you will be able to hacktivate your phone as part of the jailbreaking process. HOWEVER, the current 4.1 for all phones contains a baseband update which is not currently unlockable or downgradable (and your phone would only work on AT&T).
EDIT: Read Semaphore's blog (http://thefirmwareumbrella.blogspot.com) to learn how to use TinyUmbrella to update your iPhone 4 (and only the iPhone 4) to any newer firmware without touching the baseband. That'll come in handy if/when you update to jailbreak on 4.x but like being able to use your phone in the UK.

If your going to use tinyumbrella to go from 4.0(x) do a restore not a update. If you do a update you will update the baseband. So it is very important to just restore. I just did it to my i4 and it worked great. Still on baseband 1.59.00 and version 4.1 (8B117). Now waiting for jailbreak.
