Previously, I have covered the release of iPhone OS 3.0.1, which is a security fix for SMS vulnerability. For iPhone jailbreaker, you probably want to upgrade to iPhone 3.0.1 for the sake of SMS bug fix. However, your top concerns are:
Is iPhone OS 3.0.1 jailbreakable?
Does ultrasn0w work on iPhone OS 3.0.1?
And… the answer is absolutely yes for both questions! The iPhone Dev team has confirmed that both redsn0w and ultrasn0w work for iPhone 3.0.1:
You can re-use redsn0w v0.8 we released a few weeks ago to jailbreak today’s 3.0.1 update. Just let iTunes update or restore you to official 3.0.1 then run redsn0w. The only “trick” is that when redsn0w asks you to identify the IPSW used, point it at the 3.0 IPSW instead of the 3.0.1 one. After the jailbreak, reinstall ultrasn0w 0.9 if you need the unlock.
So, with the simple trick in redsn0w, it is safe to upgrade to iPhone 3.0.1 and jailbreak it.
If you accidentally upgraded to this iPhone OS version, simply go through the jailbreak process again (but remember to use the iPhone 3.0 IPSW in redsn0w) and re-install ultrasn0w 0.9 to unlock your iPhone.

Thanks for the post once again, it’s super easy and works like a charm! Good job Simon!
yup, it works very well! i finally took the plunge and moved up to 3.0.1 from 2.2. both jailbreak and unlock work fantastically! unfortunately, some winterboard theming still doesnt work.
Worked like a charm. I’m a t-mobile customer. I went from 3.0 to 3.0.1 using the latest 0.8 redsnow. again thanks for the detail and easy to follow instructions. keep up the great work Simon
SImon, you have been very helpful!! i have unlocked both 2G and 3G phones using ur website..
Have u come across the carrier updates when u connect the iphone to the itunes? is it to detect tethering? (especially if u have just hacked the system and not paying for it).. do u know anything about it??
Unlike normel something went wrong. I’m watching the syncing of my phone and itunes is still telling me i’m on 3.0 after i told it to update to 3.0.1??? Anyone? Was there a step somewhere in there that i could have told it to reinstall 3.0?
Hey Simon,
I have never had real trouble with these steps before but i feel like I’m missing something with the 3.0.1. I have tried twice, each time starting from scratch and making sure to follow the steps precisely. Twice now when i began to load all the old contacts and photo’s from the back up it says while doing so that it is using the 3.0, and gives me the option to update to 3.0.1 again. I have also gotten the 1406 error and i think the 0009 error on failed tries. Any idea what I’m missing? Thanks for all of the help. Don’t know where you find the time.
I just jailbroke my phone (thanks to your site for all the useful info). Before jailbreaking, I already had 3.0.1 – after jailbreak it says I have 3.0 in settings….Do i need to upgrade to 3.0.1 in iTunes again, then do the jailbreak process again?
[Help !! I can't jailbreak my iphone in firmware 3.0.1]
Condition:
- Iphone: 3GS, Firmware 3.0.1, factory unlocked
- Itune 8.0, redsn0w 0.8
As noticed, firmware is already latest. Thus, i skipped to update the firmware using iPhone1,2_3.0_7A341_Restore.ipsw. Then, I use redsn0w 0.8 for jailbreaking. It hang at process No.13 “Waiting for reboot” (And I’ve waited several hours), and never completed the jailbreak process.
Note: I try the initial step as well, i.e. to “shift+restore” using the iPhone1,2_3.0_7A341_Restore.ipsw, but itune even stated that it’s not compatible.
What shall I do? Appreciate advice from you guys.
Thank you.
Regards,
David
Hi Simon,
My iPhone 3G is currently running on OS2.2.1 and I’m ready to upgrade to OS3.01. Would really appreciate it if you verify if these are the steps that I need to perform:
1) Upgrade iTunes to v8.2
2) Restore to OS3.0
3) Connect to iTunes and update to OS3.01
4) jailbreak via RedSn0w v0.8.
Thanks!
@joanne, they are correct. But I think you can skip step 2 and directly restore to firmware 3.0.1.
Thank you Simon!
Hi Simon!
I was waiting for OS3.1 to be released and didn’t do the upgrade to 3.01 earlier. So, now that I read there are so many problems with the OS 3.1 plus the jailbreak for 3.1 Windows is not out yet, I’m gonna go ahead with 3.01. But, the problem is my iTunes is still at version 8.02 and v8.2 is not available anymore! Can I upgrade to v9.01 then jailbreak my phone using OS3.01? Thanks a bunch!
Ok, I followed this step by step and my iphone got completely fucked… “Your iPhone may be damaged and cannot be activated. We recommend visiting your nearest iPhone store…”
Tried re-virginizing by pressing home+sleep buttons, and it failed to restore to factory settings.
WTF!!
Thanks a bunch Simon! My notes:
Had an account w ATT, Skyhigh bill, closing account,
Read these tutorials but the pwnge program didn’t work on my system..
It worked until step #11 i think… whichever is the actual build process.. Locked up pwnage crashed repeatedly.
Bcuz of using an older IMac??
I have a 1.8 GHz Power PC G5
1GB DDR OS X Version 10.5.8
My Iphone is an 8GB 3G version 3.01
I finally went out an bought a wireless router. You need
RedSn0w worked after trying to enter DFU mode several several times..
But that lil program is great! I think it helped to go thru pwnge
even though it didn’t work in my case.. bcuz I understood the concept better.
Great info on here its definitely key to read through the comments.
Much thanks for laying it out so good!
Another important part for me was to Restore the phone to factory settings first
take out the AT&T Sim & install the Other Sim.. Temporarily T-Mobile til I figure out best plan.
Can we use GPS on any plan with Data?
Ok good luck IPhoners!! Now to explore cydia.. crazy style!
This stuff makes u feel like a scientist! thanks to the DevTeam and all others that
supply these tools & knowledge to the people!
Peace!!
@RecordMonster, thanks for your sharing. Back to your GPS question, it’s ok to use GPS with any data plan.
