iPhone unlockers be warned: Apple has implemented baseband signature check in iOS 4.2.1

“Apple has once again raised the stakes in their continuing cat and mouse game with unlockers by implementing a boot level signature check in iOS 4.2.1 that will cause the device to fail to boot if the baseband firmware is not correct,” TiPb reports.

“If you plan on unlocking your iPhone it is recommended that you hold off on installing 4.2.1 as there is no current method available to maintain an unlockable baseband,” TiPb reports.

  1. No problem, just give some time while the hackers alter iOS 4.2.1.

    It’s really sickening to see Apple act like this, they used to be all about user freedom. “Rather be a pirate…etc”

    Stupid Jobs, what a turd, can’t believe how he’s turned out like this, so “establishment”, such a control freak.

    What about being different?

    Don’t give me that “it’s the carriers” BS. The carriers allow 3G connect cards and dongles from insecure Windows machines with tons of malware and hacker programs on their networks. And deal with them appropriately if they violate their rules.

    A Apple user just wants control over their very own, paid for device, not the dam cell networks.

    It’s Jobs. All Jobs. We unleashed a monster.

  2. @bunches
    I think you are pissed because you can have stolen free apps anymore. What you wrote here doesn’t justify anything why you should have the freedom of unlocked phone. Don’t be cheap. Pay and buy apps. Support the developers like me. Or you can simply go to android.

  3. You can’t modify software on other devices and expect them to work properly and be supported under the original warranty.

    Duh, OS X is open to users to run whatever program they wish, including 3G cell cards and hacker software and Apple has no trouble updating the underlying operating system.

    A OS X user can enter a simple Terminal command and run their screensaver as their desktop (see MacOSXhints for details), but can’t change the desktop picture on their iPhone main screen?

    Don’t give me that baloney.

  4. @Bunch of crap as usual
    Just go away you jerk. You add nothing to MDN forums. Please give me your mailing address and I personally will send your mommy enough to buy you an android if you will just go away. Deal?

  5. All the ” freedom and independence” freeloaders that want to unlock their iOS devices should put their money where their mouths are and be fully so – Apple spends it’s resources to support users that appreciate and need it – they go above and beyond any customer support available for any product in the world, to keep their customers happy and do so at company’s and shareholders expense.

    If y’all feel so empowered and righteous in your bootlegging cheapskate and theiving ways – figure out in your teatarded logicjow to eat the cake and have it too. Don’t expect free lunches and wipe your own crap. Apple as Oracle, is aggressively enforcing copyrights, which is critical to nourishing a healthy technology industry and funding innovation.

  6. Talk about clueless people!

    This article talks about unlocked iPhones and updating to 4.2.1. It does NOT talk about jailbreaking.

    So, B & M:

    Why on earth did you hijack the thread to launch a debate (actually, a tirade) on a completely unrelated subject?

    At present, unlocking is really a non-issue in the US. It affects only two types of people:

    1. Those who want an iPhone on T-Mobile (where an unlocked US model will work, but only on EDGE speeds);
    2. Those who’re happy with AT&T, but travel outside the US and want to use their iPhone with local SIMs while there.

    The number of these is insignificant, and will likely not change by much.

  7. Oh, and buying an unlocked iPhone in Canada doesn’t help much, since the only way of using it in the US would be to (presumably) sign up with either those Go plans on AT&T (prepaid, no contract), or T-Mobile’s ‘Pay As You Go’. In either case, you are likely going to be paying almost as much as, if not even more than, the regular AT&T plan, which includes a hefty subsidy for the iPhone (making it cost only $200, rather than the full $650 or more).

    I can understand why AT&T doesn’t want to allow unlocking of iPhones. The subsidy on the iPhone is almost twice as high as any other phone (smart or dumb). Allowing people to unlock their iPhones, even after the subsidy is paid off, would swiftly move considerable numbers of those phones off AT&T’s network. Today, even the oldest, original model iPhones, are still serving on AT&T in rather great numbers. What is worst about this is, the iPhone is AT&T’s golden egg in more ways than anyone thinks.

    The subsidy is presumably paid off after your two-year contract. However, vast majority of iPhones stay on AT&T after they had paid off that subsidy. And they all stay on same rate plans, and these plans include subsidy portion. So, AT&T keeps getting that free money from iPhone owners long after they paid off for their phones. The problem is, these phones have nowhere to go, and AT&T won’t let them leave, because they don’t allow unlocking.

    If enough AT&T iPhone customers joined together, they could easily argue that after fulfilling their contract of 2 years, they must be provided unlocking instructions if requested.
