iDevices affected

Just to make sure (I don't have these devices): The iPhone 3G (even the newer MC model) and the iPod Touch 2nd generation (also newer models) don't have shsh checks. (I'm not talking about the new "soft" check.) Can someone confirm this? I always thought these mentioned newer devices also have this certificate check in the Bootrom built-in. But as someone removed my listed 3G (with a question mark), I assume no 3G has this check. What is actually the difference between the old and the new Bootrom then? Maybe someone can explain how this certificate check works exactly and which software part is doing it. Thanks. -- http 11:25, 20 July 2010 (UTC)

There's definitely no SHSH checking in the iPhone 3G bootrom. If I'm not mistaken, its bootrom can't even read IMG3 files.
I'm pretty sure the iPod touch 2G bootrom does check SHSHs, but only the one supplied in the IPSW; its restore process doesn't require getting a new SHSH from Apple's server. --Dialexio 20:08, 20 July 2010 (UTC)

Firmware 3.1(.1)

What's the difference between 3.1 and 3.1.1? Were both released at the same time? Or is 3.1 just a "short form" for 3.1.1? If yes, we should always write the full name. -- http 21:58, 20 July 2010 (UTC)

3.1 was released for iPhones, while 3.1.1 was released for iPod touches. Other than that (and the build numbers), they're basically the same thing. --Dialexio 23:25, 20 July 2010 (UTC)

Apple still signing 4.0.1 -- conspiracy?

It seems very un-apple for them to continue signing this firmware. Does anyone have any technical reasons/guesses as to why they are doing this?

I think it's sort of a truce -- in fear of yet another security problem being exploited and requiring a 4.0.3, and possibly de-incentivize the search for exploits. Possibly even more far fetched is an experiment to see if there is a boost in sales of people trying to get jailbreakable devices. Anyone have ideas? Iemit737 17:50, 15 August 2010 (UTC)

My guess is that because many users upgrade without thinking or saving shsh try to jailbreak at some point in time. Because very many users did a jailbreak by this simple page, Apple would create lots of unsatisfied users. After Antennagate having more unsatisfied users, or those returning their device just to try again wouldn't be good for Apple. Also, I think 4.1 will be released soon (less than a month probably), so they can close signing then. -- http 18:56, 15 August 2010 (UTC)
