Jailbeak and Unlock iPhone 3.1

Today the iPhone 3.1 update was released to the public. This update fixes a lot of bugs that were present in the iPhone OS 3.0 firmware. If you want to jailbreak or unlock your device, follow the steps below. If you have an unlocked iPhone 3G or iPhone 3GS do not update just yet, updating will permanently lock your device and the ultrasn0w unlocking software won’t work.
The jailbreak has not been released yet, but you can do the following to prepare for it.
How to Jailbreak iPhone 3.1
1. You must update to iPhone 3.1 first. After updating, either locate your iPhone 3.1 IPSW file or download it using any of the links below. Remember, don’t use Safari to download. Safari can’t download .IPSW files properly, use a different browser!
- iPhone 3.1 download (iPhone1,1_3.1_7C144_Restore.ipsw, 241 MB)
- iPhone 3G 3.1 download (iPhone1,2_3.1_7C144_Restore.ipsw, 242 MB)
- iPhone 3GS 3.1 download (iPhone2,1_3.1_7C144_Restore.ipsw, 306 MB)
2. Download redsn0w (not up yet, stay tuned!).
3. Follow the jailbreaking guide at the Jailbreak iPhone 3.1 post (not up yet).
Unlock iPhone 3.1
To software unlock iPhone 3.1, you must create a custom firmware that uses the current baseband. The iPhone 3.1 update updates the baseband to a newer one that permanently blocks the software unlock. A guide on how to unlock iPhone 3.1 this will be up later.

Asking of ya all If can i used redsn0w 8 firmware 3.0 then new update 9 firmware 3.1 can good working insatlling ??
what the**** did you just say? where are you from?
haha what the hell man learn english
Maybe he is learning English a$$hole. It’s not like everyone is lucky enough to be born in the U.S. English is sometimes someone’s second language, so ease up… Ha Ha Ha…..
You are right…
Please be considerate.
Maybe he is trying his very best to tell his concerns to us, as we all know that English is the main medium to communicate here…no matter where we lived.
If he speaks his own language (if he is not an english-speaking individual..), definitely, we will not able to understand him.. and you will be more pissed off. :P
I just upgrade to 3.1 firmware, when the jailbreak software leased?

I’ve been using mms since September 2 AT&T has opened it
waiting for the good new to jb 3gs in os 3.1
The jailbreak/unlock for iphone 3g was supposed to be available by last week. Any updates on that? Thanks.
AT&T MMS requires iPhone OS 3.1. We need a new redsn0w please….
I have the 3.1 upgrade and the new 9.0 itunes every time i jailbreak the phone says dowloading jailbreak data and keeps loading and does nothing for minites and shuts of what am i diong wrong
Apple is controlling the game after 3.1 updates and the jailbreak community has no answers to it. :(
Apple is like communist dictators…. They like to control their consumers coz they have the power.
I hope one day someone can changes it and make their products more freedom.
No, actually there is a Mac version of the 3.1 jailbreak. This is actually the usual Mac users general snobbery against PC users.
I believe apple has superior products to anything on the market. However, they also have superior Nazi tenancies. They control something you, and I own. They should have no influences on how I decided to use something that is no longer theirs.
Hi! I have a terrible problem. My sister didn’t realised and downloaded the 3.1 soft for the 3gs. When will the software to unblock the iphone appears? Thank youuuu
I have a brand new 3Gs which running FW 3.1 that I haven’t been able to use. I have been reading around and it looks like there are a ton of people in the same situation. Someone please come up with a JB for 3.1.
Thanks for your contineuous efforts to unlock the iphones.fighting with apple who do not care morthan a million customers around the world and do not respect of their thoughts.
here i could not understood what is the use of downloading the IPSW 3.1 and when and how to use it while jail breaking, YOU HAVE NOT STATED ANY STEP TO USE THIS FILE, BUT YOU HAVE SAID HOW TO USE IPSW 3.0 and 3.0 is recognised by redsnow but not the file 3.1
so give me a hint to jail break by using resnow 0.8 with the file 3.1 …………. and 3.0 (mixedup ???)
and again i have attempted twice to jail break my 3.1 i phone and every time redsnow stucked at “waiting for phone to reboot” and show no progress in the bar.
Hi Michael,
I got mine iphone 3gs 3 weeks ago from the UK. I charged and never used it, as is must be locked or jailbreak. Even if i inserted a european sim card it only says “No sim card installed – Insert a valid Sim with no pin lock to activate the phone” I can only use it for emergency calls.
Could you please help me, i dont really know what to do? I cant even see what firmware/version is..
thanking you in advance
