    This whole "official unlock" thing may seem extemporized from Apple, responding to a legal imposition, but you all have forgotten that after the 2 years of contract with official Apple mobile partners, these companies are commanded to unlock the iPhone (unless in US). So Apple has already thought on this matter, and the method is defined. Let's see what happen until then.

    Yeah, that would be cool.

    I could use my iPhone after 2 years, if i could activate it on my non-supported by Appel country... which means, IDK, 2 more years?

    :p

    You guys don't seem to understand, let me explain it to you in more detail:

    1. you go to a local T-Mobile shop and ask for an unlocked iPhone for 999 Euro
    2. the sales person calls a special number at T-Mobile to pass on the IMEI for the iPhone to be unlocked (alternative: the customer calls but it isn't recommended because it could delay the process)
    3. T-Mobile sends the IMEI of the iPhone to be unlocked to Apple
    4. Apple flags the IMEI on their servers as "unlocked"

    Meaning: the "unlocked" iPhone works with the same firmware and baseband like the locked ones, there is no difference. The difference happens during the activation process where Apple sends some sort of IMEI-dependent code to allow all SIM cards.

    Here's the catch: EACH TIME you connect the iPhone to iTunes, the code is re-checked to make sure that this iPhone is authorized to be unlocked. This "check" doesn't happen locally with iTunes but it happens remotely on the Apple servers, meaning that it is almost impossible to program some sort of keycode generator to fool the activation/registration process of iTunes/Apple servers.
    Theoretically (actually it IS possible), Apple could remove the unlock from the currently sold unlocked T-Mobile iPhones if they want to, for example if the court dismisses Vodafone's allegations. Of course they won't do it, T-Mobile can't afford to sell unlocked iPhones and then re-lock them again, this would not hold up in court and it won't happen.

    The only thing which may be interesting is the initial activation/registration process with iTunes when you connect the unlocked iPhone for the first time.
    Even if we find a method to generate a fake code, the next time the iPhone connects to iTunes, iTunes sends the code and the IMEI to Apple for verification and of course this would fail the verification process.

    I know, some people don't want to use iTunes, so maybe this would be a way to get an unlocked iPhone but with a limited functionality.

    Another thing: iTunes 7.5 seems to be pretty mean. Apparently it deactivates an already activated iPhone if it detects an "unauthorized" SIM card inside the SIM tray. I'm pretty sure that with the introduction of the iPhone in France and it's unlocked version, Apple made sure that the whole IMEI registration process is fool proof and I doubt there is a way to spoof the IMEI of one unlocked iPhone to make dozends of others unlocked. Apple would surely detect this through iTunes.

    Furthermore: we don't know if the iPhone sends some sort of identification to Apple servers when connected to the internet. The whole stock market app "scandal" actually shows that the iPhone actually sends some ident code (based on the IMEI) to providers, maybe even to Apple.

    To make it short: don't be too excited about the unlocked iPhone in Germany or France. If you buy one, be happy with it, it will stay unlocked. If you're hoping for a hack/crack based on the method how Apple unlocks these phones based on the IMEI, I highly doubt it.

    It is also my understanding (I'll find out tomorrow when I get my hands on a friend's officially unlocked iPhone) that you need to connect to iTunes EACH TIME you insert a new SIM in it. The new SIM deactivates the iPhone when connected to iTunes and then you need to re-activate using the new SIM (which of course isn't a problem since the phone's IMEI is flagged as "unlocked" on the Apple servers).
    I know for sure tomorrow, so please be patient, I get the unlocked iPhone for one whole day to play around with and I'll post all observations in a seperate thread.

    Here's btw a little rumour for you guys: according to an Apple source, Apple will introduce a completely new firmware, bb and bootloader with the introduction of the SDK next year. Apparently Apple wants to "seperate" the base software/programs from the third party stuff, so there will be some sort of safe "virtual" environment where the third party apps can be installed to to make sure they don't crash/destroy the iPhones base firmware/bb/bootloader. This apparently requires a complete re-programming of the current firmware/bootloader.
    So if someone were to get this phone number can call up Apple... you could pretend to be a T-Mobile employee and get Apple to unlock your phone.

Strange, apparently the menue appeared but the iPhone is still using the original T-Mobile EDGE settings, even after a network settings reset......
    thats normal, t-mobile cards allways work even without settings. only if you enter useless information in the fields it stops working.

    but i wonder how i will be able to use E-plus GPRS if i cant fill in my settings. eplus for sure doesnt work without proper settings. i'll find out after lunch.....

    if it doesnt work t-mobile gonna have a huge problem....

I still think that the currenltly unlocked T-Mobile iPhones are not something Apple ever wanted, incl. the 999 EUR iPhone. Why? Simply because they don't use a simple unlock but some sort of IMEI verifiying method which requires Apple to "flag" the IMEI as "unlocked" on certain iPhones.

    It takes up to over 24 hours to unlock the iPhone after you buy it, simply because T-Mobile sends the data (IMEI) to Apple and Apple(!) flags the IMEI manually, not a simple automatic process, probably to keep control of the unlocks.
    I don't think any company goes into court saying they won't win. Personally I doubt this was something thought up by Apple in one day, it's quite likely the same method they've been planning to use in France next week for unlocked purchases. I guess we'll know soon enough.

    Some of this discussion doesn't entirely make sense. I can fully accept that the "official" unlock protocol relies on iTunes checking and re-checking the activation status of each new SIM that is inserted, and that it re-checks previously activated SIMs each time the phone reconnects to iTunes. That process essentially occurs with all current phones, but the patched lockdownd file helps us all past the iTunes activation/checking process.

    But if iPhones by default have their modem/baseband locked to allow only authorized SIMs (regardless of what type of activation method you use), then officially unlocked phones STILL must do something with this modem/baseband lock, and it would be interesting to know what it is. Someone should run minicom on one of the phones and see what the results are of the query to check if the phone is locked/unlocked. We know what a locked phone returns from this query, as well as what an anySIM-unlocked phone and IPSF-unlocked phone returns. Does the officially unlocked phone return yet a different result?

    Again, I don't think this will help figure out a magic way to unlock everyone's phones, but I am just curious to see how it works. We still really need to find a way to write unsigned code to the baseband using the new bootloader - that's going to be the key to unlocking the current generation of phones, IMHO.

    1. the unlock only works if this is a T-Mobile registered IMEI (for your information, the IMEI is unique and Apple knows exactly which IMEI belongs to a US iPhone, T-Mobile Germany iPhone, etc.)
    2. the T-Mobile Shop calls a special number at T-Mobile(!) not at Apple and communicates the IMEI to them
    3. T-Mobile apparently sends for EACH "to-be-unlocked" IMEI a Fax to Apple to request an unlock, stating the IMEI and the date of purchase (important because the unlock is based on a court order valid starting with Nov. 19th!)
    4. Apple checks the request for being legit (IMEI check, purchase date, etc.) and "flags" the IMEI as being "unlocked" on their servers
    5. it takes AT LEAST 24 hours until all Apple servers receive the flagged IMEI and until the unlock starts to work
    6. you need to do a FULL SETTINGS RESET with the new (not supported!) SIM inside the SIM tray before you "activate" the unlock through iTunes
    7. iTunes "recognizes" the iPhone's IMEI as being flagged "unlocked" and unlocks/activates the iPhone
    8. each time you insert a new (different carrier) SIM, you need to do a FULL SETTINGS RESET to make sure the SIM works fine.

    The FULL SETTINGS RESET is NOT something you do with iTunes or something which deletes the content of your iPhone, there seems to have been some misunderstanding. The FULL SETTINGS RESET happens in the Settings menue, just make sure you don't choose reset & delete all content because this would leave you without mail account settings/music/videos/apps/etc.

    My unlock isn't "through" yet (24 hours haven't passed), so I can't say much on how the unlock works and if it requires a live internet connection through iTunes each time you insert a new (different) SIM card. I'll keep you updated.

    so, is iTunes that sets the unlock flag on the iphone?
    don't you think that will be possible to intercept the iTunes request of the details of the given iphone IMEI and reply to itunes that the given IMEI is unlocked?
    something like the first "dvd john" activation server method.

    997TT, ensure that you get the dev team's help in recording what iTunes (and your network connection) is doing when the iPhone is unlocked by iTunes.
