    Default SIM Unlock solution possible but useless?

    Everybody is waiting for a SIM unlock solution, so the iPhone is capable of using a SIM from any desired cell service provider.
    I'm pretty confident that such an unlock solution will be available sooner or later, thanks to the group effort done by the development team we all know well.

    However, there is a concern I have and the logic behind it is very simple: if Apple and AT&T are using iTunes for activation, it is also very likely that iTunes is checking the phone's software "state" and the used SIM card from time to time when it synchronizes with iTunes.

    So here's my point: if iTunes is used as some sort of "activation/lock" verification tool, it is very likely that either iTunes will block an unlocked (hack) phone completely, so you can't sync files bought in the iTunes shop or that the unlock will be reversed and the iPhone gets locked again. I think the sync block would be easier to do for Apple, based on various unique values identifying the phone AND the SIM card.

    Solution to avoid this? Maybe it would be necessary to change the SIM on an unlocked iPhone to the original AT&T SIM before connecting it to iTunes.
    I also see a major problem regarding iPhone firmware updates because any modification of the firmware (hack) will surely be reversed as soon as the new firmware is uploaded to the phone. This also would require a new unlock in my opinion since the lock process happens in the phone and iTunes and not in the SIM card.

    I'm not an expert and I know that the main goal is to achieve a SIM unlock first and to worry about possible countermeasures from Apple/AT&T later but I think that Apple/AT&T will give us a very hard time as soon as the first unlock solution is ready.

    Any thoughts?

    You are right that iTunes requires a AT&T SIM in the phone to be able to sync, I have an activated (thru the tool.zip) and just switched to a local carrier SIM, then iTunes claims the SIM isn't an AT&T one and makes it impossible to sync.

    However if people discover how the activation/locking process is done from within iTunes (as discussed in the "I still think its in the activation process" thread) it might be possible they've also discover a way of disable the AT&T required SIM for enabling the syncing. That's what I'm hoping for anyway

    If the lock is done through the itunes process then a simple 7.3.X will change the lock process so all unlocked people just wouldn't upgrade their itunes until a patch itunes upgrade was made.

    if Apple relies on iTunes to prevent "illegal" unlocking then i think it's good news... as you can see dvd jon has no problem solving that

    Software side protections can be removed in no time. Thats nothing to worry about.

    That's what iActivator was developed for: Put any SIM into the iPhone and pair it using iActivator - and iTunes will sync again.

    I'm actually afraid that the problem doesn't lie in the iTunes software itself but in the fact that iTunes communicates with some sort of "validation" server.
    Look at Windows Vista, thousands of crackers/hackers worldwide are working on a method to actually disable the WGA check but nobody actually found a method yet which works for a longer period of time.

    An SIM unlock solution would be pretty much useless if the iPhone has to be modded again after each and every iTunes version update, firmware update, etc. or if I couldn't use the sync function of iTunes anymore.
    Not to forget about the fact that we'd need to wait for the dev team to "update" the unlock hack every time Apple changes something (iTunes, firmware).

    Look at the Apple DRM: it has been cracked for earlier iTunes versions but there still isn't a solution for newer iTunes versions (6 and up) and video files.
    The Windows WMA DRM protection has been cracked twice in the meantime, just recently again.

    If an unlock solution means that the iPhone "locks" up again as soon as iTunes is updated and/or a new firmware (with new and interesting functions and bugfixes, it can't be ignored) is available, this really isn't going to work for most iPhone owners. It would be a great success for the dev team, no doubt about it but in the end it would only be more of a demonstration than a real usable hack/unlock.

    I really hope that I'm wrong.

    Mine syncs just fine without the SIM.
    It will even sync with my T-mobile SIM inside.
    With the T-mobile SIM, I get an "unsupported SIM" warning screen, but it still syncs if I right click on the iPhone icon.
    Phone still doesn't work, obviously.

    Can you sync iTunes DRM protected stuff with your T-Mobile card?
    Just curious, didn't try it. Do you have a hack activated iPhone?

    Apple can easily apply some sort of SIM check inside their iTunes software, incl. the need of a live internet connection to properly do this. Don't underestimate them, as soon as the first unlock hack is available, hell will break loose on further unlocking attempts, be sure of that. Especially AT&T has a vital interest that no unlock will be available. Right now, Apple and AT&T are sitting tight, just watching but after they learn the how and where, Apple will make it harder and harder for unlock solutions.
    I suppose Apple is bound by contract with AT&T to make sure that the iPhone keeps it's AT&T exclusivity in the US. I'm afraid this also means that some people should be prepared to deal with the whole weight of Apple's and AT&T's legal departments.
    It actually doesn't matter if unlocking is legal or illegal, no private person would financially "survive" the first couple of weeks of cost for a trial against Apple/AT&T.

    Btw: I think that the SIM unlock solution is very close (a couple of days, maximum two weeks?), so be prepared to grab it while you can because it may not be available or even work for long. The major question is: is this going to be a permanent unlock, some sort of changing of flash code inside a phone chip or just a change of firmware. Since the iPhone gets hardcoded/locked permanently to AT&T if you enter a wrong unlock code for more than 10(?) times, there may be a real chance that the first unlock solution will actually work indefinetely. I wish the dev team good luck.

    If Apple really wanted the phone to be impossible to unlock or the SIM not changeable, The SIM will be inside, like the battery.
    Of course all this effort of the community is good for Apple.

    Why do you think the SIM unlock is so close?
