iPhone, iPod touch 1.1.1 jailbreak confirmed

iPhone jailbreak confirmed

iPhone and iPod touch hackers have produced a new iPhone/iPod touch 1.1.1 file system hack that offers read and write access to the devices, as well as the ability to execute applications. Hackers jumped at the chance to try their hands at Apple's iPhone when the device shipped in late June, producing a series of 'jailbreaks' that allowed users to access the file systems of their cellular phones. After gaining read and write access to the smartphone, it wasn't long before hackers released utilities to 'unlock' the device, thus allowing users to sign up with other cellular carriers despite Apple's exclusive deal with AT&T as the sole provider of voice and data contracts for iPhone customers. Apple's latest software update disabled these hacks, and since then only one claim of a rogue 'jailbreak' -- which was announced yesterday -- capable of providing filesystem access to the tested iPhone has surfaced.

Apple warned customers late last month that unlocking their phones could damage the device, and that doing so would void the warranty. The Cupertino-based company issued its iPhone update 1.1.1 soon after issuing that warning, which entirely disabled current hacks at the time and rendered hacked phones virtually useless.

Now, Engadget has confirmed that the new jailbreak, which depends on a TIFF image exploit to gain root access to the handset, does indeed exist and that the method provides both read and write access to the filesystem.

Developers of the new jailbreak are quick to note, however, that Apple need only patch the TIFF vulnerability to disable the new hack. The iPhone hackers also added that they are still working out potential issues with the jailbreak, citing one instance where they unexpectedly lost read and write access to the filesystem.

    and now...

    we can have iBrick suits part 2.. people claiming they didn't have fair warning (still) that using these techniques would render their iPhone senseless. What a bunch of idiots. Why would anyone risk getting smacked in the head after seeing what happend before?

    It has less to do...

    with unlocking the iPhone for other networks (which did partially brick a phone and which Apple doesn't condone) and more to do with allowing access for 3rd party software (which Apple said it won't support, but sees nothing wrong with). The main problem remaining is that the method for installing the software is a security hole (one that would be very hard to exploit for nefarious reasons, but a hole none the less and one Apple will most likely plug at some point).

    Here's to hoping either a more secure way of adding 3rd party apps is found by the hacking community, or Apple will feel it's time to release an official API in the not too distant future

    1.1.1 Success!

    After reading through the ridiculously long instructions online, I have successfully downgraded, installed installer app and then upgraded to 1.1.1 firmware. All of my settings, etc were saved (even Youtube bookmarks) and then all of my info was synced back to the iphone when finished. Everything on the phone works normally and almost all 3rd party apps (the list is much shorter now) seem to work fine. NES!! However, summerboard and customize do not work and I had to uninstall them because they were shifting icons around all over the place :( Anyway, if you can make it through the can have 3rd party apps again. It's worth it! My 2 cents.
