If you are an iPhone 3GS user who has accidentally upgraded to iPhone OS 3.1 as you weren’t aware of the warning given by the iPhone Dev Team to avoid upgrading to iPhone OS 3.1 then there is some more bad news.
Folks at BigBoss are reporting that iPhone 3GS users who had accidentally upgraded to iPhone OS 3.1 can’t downgrade to iPhone OS 3.0 or iPhone OS 3.0.1.
They are reporting that Apple has stopped signing iPhone OS 3.0 and iPhone 3.0.1 firmware files, which means that iPhone 3GS users cannot restore using any firmware files. They can only restore using iPhone OS 3.1 firmware file.
According to them:
“1) If you have an iPhone 3g or 2g, you are fine and should be able to restore.
2) If you have a 3gs, you can only restore 3.1 (and kiss your jailbreak good bye). If you did not get an IBSS/IBEC signature before now and you restore, you may never be able to jailbreak again.
3) If you have an iPhone 3GS and you used Cydia to save your TSS or did purplera1n or similar a while back and saved your IBEC, then you will be able to restore in the near future, but you must wait for someone smart to write a utility that will let you do it. Chances are good that such a utility will come out in a couple days. If you can be patient and wait, do so. No one wrote this utility prior to this because we were not sure if Apple would actually stop signing 3.0 - only that they *could*.”
There might be some glimmer of hope for iPhone 3GS users as they have also pointed out to a tweet by chronicdevteam, which claims that iPhone OS 3.1 GM is still vulnerable.
It looks like the cat and mouse game between Apple and iPhone Hacking community has got more interesting with Apple making it even more difficult with the introduction of iPhone 3GS and now by not signing previous iPhone OS firmware files.
We’ll keep you posted on this developing story so please stay tuned here at iPhone Hacks.

Thank you, i will wait for the dev Team to come out with the solutions
HELP PLEASE… i tried to jailbreak & unlock my white 16gb iphone 3gs 3.0 using redsn0w 0.8.. after running redsn0w, my OS was gone.. it only shows the cydia & icy icons. i can't restore it thru itunes, it says "version not verified". and i don't want to upgrade to 3.1.
HELP PLEASE… how can i bring back my precious fone back to life.. i'm only using this for 2 days. can't bring it back to the store coz this unit came from the US..
The iphone 2g is still capable of being jailbroken/unlocked. If you upgraded to 3.0.1 or 3.0, you can still jailbreak with redsnow. Just use the 3.0 firmware and make sure your prepaid sim card is not in the phone. Then put the card back in when the process is done.
I just ordered a new iPhone 3GS from my local AT&T store yesterday on direct fullfillment. It is supposed to be in Friday morning. Does anyone know if these new iPhones will have 3.1 factory installed or 3.0… I will be LIVID if I don't even have the opportunity to jailbreak my phone since OS 3.1 cannot be downgraded. Hopefully, they are still shipping out 3.0.1 or less. With my luck though, I would buy my iPhone 3GS 1 week too late!
Update: If this is the case, I am cancelling my order and just going with a 3G. So someone please let me know soon!
pls f u can tell me how can 2 remove my 3.1 software nd put 3.0 ??
my i phone is the 3g??
so pls tell me how nd from where?/
thanks
Hi,
its false, you can downgrade 3.1 to 3.0 with an 3GS iphone.
So your baseband will keep 5.x and Firmware 3.0.
Using a false host with itunes 9 (Itunes can't contact real Apple server).
Can have pb with the reboot (the iphone can rest in recovery mode) but easy to resolve with Irecovery.
I´ve got a 3G
yeahhhhhh …. oh my god. BigBoss managed it for the lucky 05.08 bootloader version. And thank god its me

There is a new version of fuzzyband 3.1 gm in cydia. I could flash my baseband from 05.11.07 to 04.26.08!!
Ultrasnow and ….Yessssss Carrier signal is back again!!
Thank you sooo much guys. You are the best!!!

You don´t know how happy i am right now…
all the best

I recently purchased Iphone 3gs with installed OS 3.1. So can I jailbreak or unlock my Iphone?
I got this problem as well please advice: i downgrade to 3.0, then jailbroke the 3g iphone but still no service. The carrier is At&t. Thanks
If you used PwnageTool to jailbreak your iPhone, then you should deselect
"Activate the iPhone" option when you jailbreak it if you are using the
official iPhone plan.
I use windows so i did it with redsn0w 0.8
Strange, are you using an AT&T's iPhone plans?
Thats correct. The baseband is 5.11 so dont know its that the problem.
i got same problem (install sbsetting)
i let the phone on off by itself over night. it works for the first time.
but i never learn -> crash again
this time , iphone on but only apple logo no screen for more than a week already.
i don't know what to do now, just wait…
Alright im sorry imma noob at this but i love iphones. Been thru many so far. Ok i bought a 3gs worked and everything but 3.1 os. Like a dummy i tried to downgrade it and now my iphone i believe is locked in dfu mode no matter how many times i try to get it out it would show a picture of a usb cord plugging into itunes, OR! It gets me to the point where it says NO sim card installed. Insert a valid sim with no pin lock to activate phone. Right now i dont care about unlocking or jailbreaking it but i wish i can atleast get it to the home screen so it works. Can someone help me please.
I have a 3GS, it was running 3.0.1. I did jailbreak it with redsn0w, all went well. Then I tried to unlock it with ultrasn0w. Followed all steps correctly. After the final step the phone won't reboot. Stuck at the apple logo for 30 sec then blank screen. iTunes won't recognize it.
Any ideas what I could do to get it to reboot and not having to restore to 3.1? I opted for having my signature stored by Cydia if it can help.
I tryed to jailbreak my iPhone 3GS, but Iam not the computer type, so silly of me, I updated it to the newest version. But it wouldnt update, there was an error. So now the phone just stands in iTunes-mode. IF ANYONE knows how to fix this, could you save my life and send me an email on how to do it? robi__1@hotmail.com
please guys!
