Infineon is the one that creates the baseband program and it's bootloader. So far the design is for a fixed baseband bootloader and a flashable baseband firmware.

    Upgrading the bootloader on existing phones is too risky for Apple/Infineon: there will certainly be bricked phones.

    And yes, if they make new bootloaders upgradable, then they will be making it even simpler to downgrade or create a custom BL.

    Now, the tricky part is that in the upcomming 3G model, the baseband will have to change and ...... the game will start again.

    A new bootloader soon? hummm... with a new baseband in the horizon?
    Guys Let's stay realistic please. A bootloader cannot be made upgradable since its purpose is in fact to offer "restorability and upgradability" to the other software components like baseband and firmware. Now, even for a genius like Geo the next bootloader version will become a real challenge (everytime a flaw is found it is patched in the next version) and there is absolutely no warranty that the next one will be even hackable. So if you want a new iphone go and buy it when you are sure that one can be hacked

    There always will be exploit in the bootloader. There are two reasons:
    1. It is human made
    2. Apple makes tons of cash because of those hacks. That is huge benefit for them to clean their hands with hackers in front of their partners and at the same time to sell like crazy. If they just care to their contracts with partners be sure the technology allows to do unhackable things, but in this case they will loose that 500 millions from the unauthorized used phones and even more, why the phone was hacked several days before 14th February?
    Because lots of young people are going to give the dam iphone as present and apple will sell like crazy the phone that almost everybody forgot to buy because it is unhacklable
    Because of course good chance to get rid off from all that phones which are staying in the stores
    Because they will soon release new models (just like 16Gb one)
    Because the profit goes down and the stocks are going down( for one moth they lost more then 10% from their value )

    Good business plan from apple marketing but they should definitely sent a check for at least $1 million to GeoHot because of that hack which makes them even more profitable.

    do you accept everything people tell you?! with all the respect, Geo is regarded as "God" in the hacking community, and he has put life into our phones.. but who really knows how long it actually took him to unlock.. one thing for sure, he is much more productive than Dev Team or Elite Team combinded.

    no.... if you are from US then there is a very small chance 1.1.2 is 3.9
    but usually its 4.6
    anything less than 1.1.2 is 3.9
    1.1.3 is 4.6

    i am not sure what week number 1.1.2's have 3.9 but i am sure someone will confirm what it is
    Is there a current list of weeks with corresponding firmware and bootloader versions somewhere?

    Reliable? How is that reliable? They cite a site that is down! And besides anyone can claim that they will target the next release of firmware.

    I know a few apps that are being developed and waiting to be released only when the SDK is available.

    Apple is definitely going to care if the iPhone keeps getting hacked.

    The profit on the hardware is insignificant next to how much Apple makes in kickback from the likes of AT+T, o2, T-Mobile and Orange.

    Let's say they make $160 (40% margin) on each handset, then that's 160 million profit from the 1 million unlocked iPhones.

    The analysts reckon that Apple have sold about 4 million iPhones to date, so that's about 3 million on contract. Given that they get around 20% of all contract revenue, that's a huge chunk of change.

    If we assume that all subscribers are on the minimum spend ($59.99/month) for two years, and we say that all those sales are in the US (to save me having to work out currency conversion etc.), then that's a kickback of eight hundred sixty-three million eight hundred fifty-six thousand dollars.

    This ignores the $200 that AT+T is supposed to be giving Apple as a one off payment for every new subscriber the iPhone attracts.

    Given that not everyone will spend the minimum, you can safely say that the total kickback over the two years will be closer to one billion dollars.

    If you were Apple, you'd definitely be worried about losing a billion dollars, and would want to do everything possible to stop it from happening.

    I think we can safely look forward to newer, more secure bootloaders with each successive release. They'd be mad not to do it.

    Bagpuss.
