Apple Blocks 3GS Downgrades, iTunes 9 is Safe, 3.1GM Vulnerable

Posted September 10, 2009 at 10:16am by iClarified · 40081 views
Since the release of iTunes 9 and the iPhone OS 3.1 yesterday the Dev Teams have been busy analyzing the software to find changes.

Here is the current status...

- MuscleNerd confirms that it is safe to update to iTunes 9 for those who have already jailbroken/unlocked.

- saurik has noted that Apple has blocked the downgrade to 3.0 for iPhone 3GS users. This means that he can no longer signature hashes for users. Users who have saved their ECID SHSH information will have to wait for someone to build something to use that information. We will post more explaining this in the near future. In the meanwhile you may want to look at this (Windows, Mac) tutorial.

- chronicdev has confirmed that the iPhone 3.1GM is still vulnerable

- the new firmware does include a baseband upgrade which will cause you to lose your unlock unless you are on the iPhone 2G or have an iPhone 3G with the 5.8 bootloader. If you do have the 5.8 bootloader please note that no tools are available to perform the baseband downgrade yet.

- it is NOT okay to update to 3.1 if you are jailbroken or might want to jailbreak in the near future. WAIT!

IPHONE CONFIGURATION UTILITY VERSION 2.1 My main concern is, I have a jailbroken 3G S should I have installed it? What effects will this have on my iPhone being that it is jailbroken? I also have iTunes 9 as long as I don't do any 3.1 update to my phone I should be ok, right. thank you..

i have a J/Unlocked iPhone 3gs with3.01. i downloaded iTune 9 and it is working fine: QUESTION: can I download and install the " iPhone Configuration Utility Version 2.1" or will it cause problems with my Jailbreak and Unlocked iPhone.

I have a 3gs on 3.0 FW and I successfully JB'd & unlocked. After JB'g, I wasn't aware I needed to reset the phone before adding other cydia applications. My phone started crashing, but I was able to get it to come back up once. Since then I can't get it to boot up properly. It just keeps displaying the apple logo and the screen goes black. I've tried to run redsnow, but keep ending with an error message toward the end about an incorrect block count for file data_a rk.plist (it should be 1 insteas of 0) Invalid index key (4, 1) ** Rebuilding Catalog B-tree. disk0s2s1: alignment error. ** The volume Data could not be repaired . Mounting rootfs as read-write... Mounting devfs... Mounting disk0s2s1... ERROR! It stops at this point and staying at the program screen and does nothing further. Please Help. I have not updated through I tunes because I don't want to increase the baseband. My phone is not operable. Please assist???

Wait, are you saying that you are profiting off of the work of others and then have the nerve to ask a question here about that work? On behalf of those that have not told you to do so already, I encourage you to fuck off and do your own work asswipe. Thanks in advance.
jorgealina - September 13, 2009 at 12:41pm
wow does it look like i care what u said....i still make money off it anyways so i guess ill be the winner regardless of what u say or do

You will make money for sure but you will always be a scumbag. So if you can live with being a toilet bug, so can I. Maybe that money will come in handy if you or your family gets cancer or something. What goes around comes around. Please kindly fuck off and die. I really mean it.

If you don't have the original sim card the iphone will not be recognised by itunes. It seems you are waiting on hacktivation, which will come on stream IF and WHEN DevTeam find the necessary exploits for the jailbreak and unlock. If you don't have the original simcard your goosed, you wont even be able to use it as an ipod. Lesson learned here folks, always better to wait until your told to update like with all updates to iTunes and the iPhone

I presumed you were 3GS, you have a much better chance of getting your jailbreak back but your bootloader has been updated so there is nowhere to go for now. Wait on news from the Dev's, they will either exploit the new bootloader or enable some way of downgrading the bootloader. Either way you have nowhere to go for now but you must have faith!

whew, i just hope iphonedev team will finally solve the problem, anyway, i am planning to buy Iphone 3G , probably it will be an at&t prepaid kit, and will jailbreak/unlock it. Does iphone 3g also affected by the recent problem faced by iphone 3gs users?
Liz - September 11, 2009 at 3:43am
I want a straight answer. Here's my dillemma. I am worried that even if I will be using Itunes 8.2 version and OS 3.0 and the appropriate redsnow program and ipsw, the Iphone 3Gsthat I am planning to buy by October will not be jailbreakable/unlockable? Am I getting the right infos? Pls someone help me.
p..e - September 11, 2009 at 3:57am
There is no straight answer, maybe things will become clearer by the time October comes. If you can, buy the phone today as it will not be factory 3.1 and you will have a better chance of a jailbreak and unlock.
Zeljko - September 11, 2009 at 5:59am
That was a good answer.
