NCK Pattern: 6 So Far: No German pattern

So far I have (see title) NCK <=> IMEI combinations. I can't post them, since they are sensitive data of the people who were kind enough to extract their a.plist for me. I have learned that the German ones use "SP" instead of "NO". Also the two German NCK's I have both start with the number 3. Coincidence? Keep these a.plists flowing, could people please posts requests on their respective language iPhone forums? Also the algorithm used to verify the NCK on the phone is known and is not even close to reversible. Brute force is capable at 100,000 k/s, so the initial idea of finding a pattern in the NCK's is to lower the time required for that brute force.

Also my theoretical NCK generation system; this has no basis in anything anyone has discovered but... IMEI^d mod n, where d and n are relatively prime and n is similar in size to the IMEI. If Apple keeps d and n secret, they could generate NCK's given an IMEI when no one else could.

NCK Length=15

So thanks to the magic of an activation emulator and the original work of Dvd Jon, I got the activation/unlock record of a French unlocked iPhone. The field looks like

"UnlockCode" = "NO=111111111111111&";

with the 1's replaced by the code. "NO" is the lock type. There are fifteen digits, so I'm pretty sure the NCK length is 15. This is out of range of a bruteforcer, and I doubt, although its possible, that the NCK's are based off the IMEI/DevID. I would think Apple just has a big lookup table. Although any visible pattern would shorten the brute force time. So I still really need a.plists off legal unlocked phones.

Unlock ETA and NCK Length

Well I'm back to my original statement that we have to wait for a baseband update to finally unlock the new bootloader. The two exploits I posted have implementation problems. Once we get the new version, iEraser and iUnlocker will work as before. Still only hardware though. I spent the last week and a half of cold Swedish nights looking for more practical exploits, and found none. Perhaps someone cleverer than I will find one?
Also, anyone out there with a legally unlocked phone, either French or German? Could you do me a favor and download this and follow the enclosed instructions. Its a good way to get your name on the blog

2. The only problem with that is that people who have a legit unlocked phone probably wouldn't be looking in these forums. So if anybody knows anyone who has a legit unlocked phone, send them this way.

That's gonna be a hard option, unless there is a Mass Email or PM sent to all members on this board.

4. So this may trick itunes into thinking it's a german officially unlocked iphone right?

5. I have two new iphone (with the new bootloader) activated w/ att through itunes. I don't mind helping, but what exactly do you need me to do? How do I a.plist or whatever.

7. I actually have a friend overseas in the UK who just purchased an unlocked iPhone... I'll try to contact him and get him to this thread. He hasn't been online much due to school, but I'll shoot him an e-mail and see what's up.

I'm excited about cracking through the unlock, that'll save a lot of people frustration and money.

If your phone is OTB 1.1.2 that solution will not work. It also says it at the bottom in bold print. That method will only work if you UPDATED to 1.1.2. AS of right now there is no way to unlock your 1.1.2 OTB iPhone excpet with TurboSIM.

11. yeah i kinda realised that after the fact that i took the time to read it my bad sigh the quest goes on as it is

Im from australia, and i got an iphone for christmas, when it was sent over it was all unlocked and worked fine, so we threw away the american at&t sim card that didnt work. Then christmas morning, again it worked fine, i plugged it into the computer and itunes told me to update itunes for the iphone to work, now my iphone is telling me i need the original at&t sim card to activate the phone, if i get the sim card will my phone still be unlocked, and if no how will i unlock it again? and does the installer need phone reception to download things?

13. try the stealthsim. it unlocks version 1.1.2. got it on mine from www.iphonelocks.com

15. has any progress been made with this?
