Apple Has Stopped iOS Downgrading
An anonymous reader noted a forum post seems to confirmApple will be
fighting downgrading in iOS 5. Quoting:
"This will only affect restores starting at iOS5 and onward, and Apple will be able to flip that switch off and on at will (by opening or closing the APTicket signing window for that firmware, like they do for the BBTicket)."
You live by the wall, you die by the wall.
Disagreeing with me does not mean you get to mod me troll.
I have faith the Dev Team or someone will figure out some sort of work around. Otherwise, it has never been officially enabled anyway which is just a crazy setup. It's nonsensical to not allow people to change versions of iOS. Lots of iphone 3G people I am sure wish they could switch back to iOS v3 after finding v4 too slow. I understand security holes plugged might be part of the reason they do this, but since Apple stops supporting some of the devices (iphone 3G and iphone 1) anyway, it can't be why they don't allow downgrading...
I found when I upgraded from iOS3 to iOS4 on my 1st gen iPad it caused it to work sluggishly. I was considering going back to iOS3 if possible and I'm even more afraid to go to iOS5. I got the iPad at xmas and not even 6 months in I felt I'm already behind in performance.
More like Apple has implimented another annoying, eventually to be circumvented, impediment to downgrading.
Hey, how's it going?
Speaking from experience: I had a less-than-a-year-old iPhone 3g, which got semi-bricked when I installed the iOS 4 update last summer (stated as compatible, as in Vista-compatible).
At the time, I was able to downgrade back to a previous iOS release; but, being unable to call even emergency numbers for minutes (oh, if the phone didn't crash entirely) until they fixed their memory-hogging, badly written OS months later (iOS 4.2), would be a very bad thing.
That depends. Do you love Apple products and think that they provide a slick, productive, secure intrrface? If so, this is wonderful news. Do you hate Apple and everything they stand for, and detest the idea of compromising your freedom for the safety of a walled garden? If so, this is draconian fascism that threatens the foundation of western freedom.
You live by the wall, you die by the wall.
Yes, better to use Android, where there are no restrictions on downgrading.
Indeed, you're probably stuck with the older version, since your device manufacturer probably doesn't support anything except the version it shipped with. But there are not actual restrictions on it, so everything's cool.
Until iPhone security is implemented with RSA or other public-key crypto system on chip, the cycle of crack and patch will be for us onlookers an amusing game of quoits, or maybe as a slap-fight at a Wild Irish Rose festival. For Apple, though, the stakes are higher than kids getting to play $0.99 games for free, as each exploit is a proof-of-concept that both questions Apple's entire design, implementation, and review process and demonstrates to businesses that their trade secrets remain low-hanging fruit on the iOS platforms.
I feel that their objective is simple.
They release an "upgrade" that degrades performance on older phones. People update because of the new features but soon decide it is too slow for their taste and try to downgraded back to when it was ok.
Since now they won't be able to, and their phone is ruined, they decide they need a new phone. But all those apps they bought are stuck to iThings, so, not wanting to lose them, they buy a new iPhone.
*Sigh*
This is why Lulzsec stopped they're 50 day vacay... to focus all their attention on making iOS down-gradable.
It implies that Apple ever condoned or deliberately enabled this. They are strengthening their protection against an activity that they never intended to be possible. You might as well post "Apple Stops Jailbreaking".
I don't understand this guys trying to fight a product which tries to lock them down: Don't fight it! don't buy it! period!
I've been using the beta and now beta 2 on both my iphone and my ipad. As of beta 2, you can now sync wirelessly, but syncing in general has become somewhat unreliable. Lots of wierd errors. But I'm not going to go up in arms since it IS only a beta.
However I've found the wifi usage on my devices to be significantly improved. I was hoping my 3g stability would improve but it still sucks. But my phone is a 3gs and I haven't noticed any issues performance-wise. Ditto with my Gen 1 ipad. So far I'm quite happy with the improvements Apple has made.
Possibly an English language translation would benefit those people not fluent in Apple. Is this more of a "hurray, Apple have finally put a stop to the scourge of downgrading" or more of a "booo, why are Apple stopping people downgrading"?
This is more a "Huh, Apple has finally closed the loophole we were using to allow downgrades but we all knew this was coming."
If all else fails, immortality can always be assured by spectacular error.
People will now have to ditch them sooner because they become unusable and sluggish after a few firmware updates..
This really was an inevitability. Gives apple version control, and helps close the game of cat and mouse between developers. Even though it seems apple has taken a much less aggressive stance in completely stopping jailbreaks. (IOS 5 beta still exploitable by devteam exploit)
Apple has been fighting the downgrade for sometime now starting with the 3GS and the required verification signature through the apple servers hence the 3194 error you get when trying to downgrade your OS version on a 3GS and now 3G with newer versions. There are of course ways around it (using custom builds) but it just makes it more of a hassle. ANd thankfully for stuff like TinyUmbrella you can save your baseband and restore to it. I don't know how this will work with IOS 5 but I'm sure there will be a fix for it.
The difference is that the restore is done on-device now (over the air updates). And the device sends a nonce to get an APTicket.
The restore app must be hacked to save the nonce and the APTicket together, and now since the app is on the device, it's going to be more difficult than it was before.
Apple never wanted downgrades before, that's why they stopped signing old code per device a while back, hence the "save your blobs" movement.

Or at least the ones who can't afford a phone solely devoted to running beta iOS releases.
If I can't return my wife's iPhone to its supported state after loading a beta release, I can't load that release.
To a Lisp hacker, XML is S-expressions in drag.
You're forgetting all of the people who sit in between and both love the slick styling AND the ability to customise their own device how they like. This move doesn't really affect people from group A (they want the security so more security is only good for them) or group B (they hate the current level of lock down so more of it won't change their minds) but it has a huge impact on people from group C who now potentially have a sacrifice to make either way.
Bon appetite!
xkcd is not in the sudoers file. This incident will be reported.
Being able to customise their device and install any old rubbish on it would ruin the device. I am convinced that a mobile device can only be as slick and solid as Apple's devices by being within a walled garden. As soon as you knock down the walls, it is inevitable that weeds will get in. Or, is the state of Android not as bad as it seems? I'm willing to change my mind if I'm wrong.
That depends. Do you love Apple products and think that they provide a slick, productive, secure intrrface? If so, you don't care. Do you hate Apple and everything they stand for, and detest the idea of compromising your freedom for the safety of a walled garden? If so, why do you fucking care
FTFY
There's been lots of Android customization without terrible problems. Just look at the default widgets, lots of customization options there to start with. I enjoy having a simple toggle for things without having to go through piles of menus. (wifi, wifi sharing, bluetooth, etc)

And this is why Apple has joined Sony in my DO NOT PURCHASE list
Ever since the fiasco of the slow-as-hell iOS 4 on the two-year-old iPhone 3G, I tell people to think twice about upgrading your iOS version. You will not have the same, snappy phone as when you bought it. And now they have made downgrading impossible -- I think it's a bad move.

My 3GS is cludging along with iOS 4.3.3. I don't even want to see how it will run under iOS 5.
