When the bootloader is not the bootloader...
I'm exit to address the deuce comments I acceptable in this post. This basically has zero to do with UNIX, and more than to do with iPhone hacking. There's a lot of mental confusion around with the jailbreak/unlock. The deuce comments basically hit upon the piping points. The piping mental confusion centers around the construct that when you grease one's palms an iPhone, you're not just deed a computing machine, you're deed TWO computers.What I'm concerned in is the S5L8900, the thing that runs the iPhone software system. Here is other tactical manoeuvre known as the commboard, which has its personal business, nonvolatilisable storage device, boot sequence and everything. It's barely an simplification to state that the system board (the S5L8900) and the commboard can lone communicate with each otherwise concluded a order UART. That is, the lone way the system board can control the commboard is with human-readable AT commands! Not precise low level at no; they're not precise interconnected. Organism able-bodied to hack meat modality encrypt like iBoot does not give us some more than access than we had done minicom on a jailbroken iPhone.
kavkan asked me if iPhone UNIX would head off the unlocks. He point started talk about golf shot on third-party applications, etc. Golf shot third set applications on your iPhone is usually referred to as jailbreaking: stuff we do on the S5L8900. When we say unlock, we're usually mean a SIM-unlock. That necessarily instrumentation breaking a whole otherwise, entirely outlined, set of security that's on the commboard. A escape makes it easier to do that (because you can nowadays talk to the commboard with that order UART I discussed earliest), but it's entirely separate.
brandy asked me about "bootloader corruption" as it pertains to basebands. As I same earliest, the bootloader I am talk about is on the S5L8900. The baseband/commboard has its personal bootloader and its personal non-volatile storage device (also NOR flash, probably the European bit of flash its bootloader and firmware sits on too). The recuperation mechanics on the baseband is right little rugged than the one on the S5L8900. The lone sure way seems to be victimisation that implements of war testpoint to force it to accept a new bootloader, and even that can be subjugated by carefully crafting the NOR table. In otherwise language, it sucks.
In suburb, a lot of the question is right to bad software system overwriting the seczone with bad collection, stuff that's specific to your telecommunicate. Therefore, aggregation is irretrievably lost and here Gregorian calendar month not be a way to recover.
The repudiation is, of course, I'm not a baseband practiced. This stuff is lone what I've surmised by supporting out with no of them. It's openhearted of strange. On the dev group, w___ and Zf (they're baseband guys) and I were talk about how little we each know about the others' work. We do beautiful little the European work, but on dissimilar platforms. Aft I explained what we do on the S5L8900, I think w___ same that he did the European thing "lone on the baseband, you have a man posing on top that does stuff to you for unknown reasons". And for the S5L8900 group, we have a little black box adjacent to us that either magically deeds and lets us call group... or not.

Exposure
Masks and witticism stuff!
We’ve had a total 39,317 downloads of the PwnApple mask in the last 7 days.
Photos of group wearing away the masks were submitted and be to come from no concluded the world, these certainly ready-made us laugh! Deciding by the comments least of you guys enjoyed the photos. Ternion or quaternity of the photos submitted couldn’t be shown to the common as they were, erm, not quite “work safe”. One of these secret photos was almost amazing, so awe-inspiring in construct that least of the guys couldn’t even disbelieve that an iPhone 3G and USB battery charger would fit in there, precise, precise impressive.
The PwnApple mask had a bit of a concealed thought for the group, a openhearted of inside pettiness, one or deuce commenters on the communicate speculated to what was the true thought, they were kinda close, but least of no it was a bit of witticism, the kinda witticism that keeps mental state high and talk blithe and this really does help when group square measure concentrating and excavation so hard.
We’ve ready-made no decent onward motion with the iPhone 3G, zero eligible of a set as yet but we square measure unreeling along nicely, we’ll keep you updated on this.
We were thinking a ‘funday’ video recording for twenty-four hour period 4-hour interval but real life has got in the way again and a small indefinite quantity of us have been engaged so we won’t have time to get it out. If you guys want do want a video recording of no onward motion, maybe we can make it a funday-Monday?
Update warning!
Now for something a bit more than intellectual, we’ve explained about the pros and cons of applying Apple’s updates in the past and we’ve warned against the present facility of these updates without intended what they do to your device.
This is indeed true of the iPhone 3G’s approaching 2.2 release. Commencement ‘2.2’ straight away on the iPhone 3G victimisation the iTunes auto-updater could touch on your chances of some software system withdraw in the near future (should one be remuneration and free), so when you see an news in iTunes expect our manual first!
Please don’t blindly instal the news and point kick about it early ;-)
iPod Touch 2G
We square measure not excavation on the iPod Touch 2G at the moment, we certainly have interest in this papers as we have mentioned before and we have finished no athletic competition analytic thinking, but currently no persuasion square measure still on the iPhone 3G, we hope to pick up work on the iPod Touch 2G erstwhile in the near future and when we have some updates relating to this we’ll communicate about them here.
