Download Custom Firmware to Jailbreak and Unlock iPhone 3GS 3.1 [Mac/Windows]
[img source : Apple.com]
iPhone 3GS users can now safely update to 3.1 firmware without updating the baseband (for unlock). If you are not the one to download all the various files and just want the ultimate result, these files are waiting for you to download! If you rather want to start from scratch, download Pwnage 3.1.3 tool for Mac.
- Caution #1 : Please proceed further ONLY if you have an iPhone 3GS. iPhone 2G or 3G owners should follow this guide instead.
- Caution #2 : A restore is going to wipe the iPhone clean. Hence, please backup your iPhone using iTunes and then proceed.
- Caution #3 : Don’t install Winterboard just yet. There are some issues that need to be ironed out for 3.1 3GS iPhone.

Do I have to use Ultrasn0w for unlock or Purplesn0w will still work
Only Ultrasn0w. purplera1n is not tested for 3.1 and is not recommended.
I had a 32GB 3GS version 3.0 jailbroken with Purplera1n. I used the custom ipsw listed on this page and it worked flawlessly. After restoring my phone I did not have the carrier logo as mentioned by several posts (you have the signal bars and wifi bars just no At&t logo. Just download "Make It Mine" from Cydia and put in whatever you want. If you want to save yourself a lot of time re-installing Cydia apps, download "AptBackup", not "AppBackup", from Cydia. Simply run it, select Backup (which takes about 2 seconds, then sync your phone with iTunes. It creates a list of all your JB apps and stores it within your iTunes backup. After restoring your phone with the custom ipsw file listed above, and restoring your files back through the normal sync process through iTunes, launch Cydia and download "AptBackup" again. Launch the app and select Restore. It will obtain all of your JB apps from Cydia and install them for you, mine kept most of my app settings as well! Have fun!
Awesome! Those are the steps I generally follow. AptBackup is a hit or miss sometimes unless you do it right. Nice tip, thank you 🙂
is it possible to go back to 3.0.1 after the upgrade to 3.1?
I am yet to try that. Definitely not possible the Apple way since the firmware for 3GS should be signed but using Saurik's replay server, we may achieve it.
thanks. i'll wait for the newer firmware then. i've heard about battery life problems in 3.1 and i don't want to risk it. please let us know here if you've made it with the downgrade. cheers.
Sure will do! I prefer 3.0.1 for the tethering option!
If not needing an unlock, using ATT service, will you still need to install ultrasnow with this method?
Nope, you don't have to use ultrasn0w if you are using AT&T.
Thank you very much. I was using a custom ISPW from a UK user and was not getting any service. Used your file and working great now! thank you again.
Awesome! Please don't install winterboard yet. It is messing the 3GS..
Do you see the carrier? Everything works right?
thanks for the custom IPSW, I have a question, my 3gs is jailbreaked by redsn0w, can I still use the custom ISPW with the shift+restore in iTunes?
Yep, you are all set to use this custom firmware.
If anyone runs in to restore error 1600, try restoring in Recovery mode not DFU mode. If you're in DFU mode, hold both the home and power buttons down until the apple logo appears and then let go and let the phone boot back up. Turn off your phone and hold the home button while plugging the sync cable in to get into recovery mode and then restore with the shift (or option) key.
Just tried it on an iphone 3gs running 3.0.1 with jailbreak and unlock. I don't need the unlock and I am an official at&t carrier. I have windows vista and use firefox. I did all the steps above and came up with an unknown error occurred (1601 could not restore in itunes), any ideas of what went wrong and what I can do to get it back. I know I can restore through apple but want to keep my jailbreak or revert back to 3.0.1.
Thanks for all the help if you can answer this question.
Just tried again and got error 1602???
Please try restore mode or DFU mode and try again.
Well I just took my iphone 3gs off the usb on my windows computer and held the home button and the on/off button for 10 seconds. The apple logo popped up and it was back to the way it was before I tried anything above, So is 3.1 really worth the headache at this point? i would like to have it to arrange my apps and get some new picture apps with zoom. Any ideas? Isnt DFU mode also if you hold both buttons down for 10 seconds unplugged from the usb port, then let go of the home button while plugging in the usb to the phone and you get the picture of the usb connecting and you jailbreak from there. Is that the same as explained above?
Watch the DFU mode video linked in the article. With DFU mode, you won't see any cable logo on the screen.
Was your iPhone 3GS pwned before (At 3.0 or 3.0.1)?
hey. thanks for putting this up. I've used two other ipsws and had "no service" problems so I'm hoping this one will solve that. any way someone can put the two parts for the non-iphone contract ipsws up on a different hosting site other than rapidfire? mediafire would be amazing. or help overcoming the no service problem would also be great! i'm running iphone 3gs, custom 3.1, unactivated ipsw but getting no service or wifi. i've tried everything obvious like reset network settings and switch on/off airplane mode etc.

Thank you for the download. I installed the Activated version (t-mobile and etc) but my carrier log is gone. The "network" under "about" shows unavailable. Now, I would like try the Non-Activated version since I do have an AT&T contract as well.
1. Does the non-activated version update the baseband ?
2. Can re-rejailbreak the phone with 3.1 Custom FW again if I am currently on 3.1 pwned FW?
3. If the network shows unavailable under " about" page, can I use the tethering option if my oversea carrier didn't block it? I was on 3.01 without the tethering hack, tethering option is available when I put my oversea simcard inside.
Many thanks in advance
1. Custom firmware has the old baseband, be it activated or nonactivated.
2. Yes!
3. 3.1 doesn't do tether… Only 3.0.1 so far. Not sure about other carriers…

I used This method but had to do it via restore mode method! Everythings back except I have no voice mail! I called AT&T and voicemail is turned on and I can retrieve voice mail from a land line but nothing on the Iphone! All New apps that require 3.1 install and work fine and all Jailbreak apps are fine also! Any Ideas on the Voice mail problem?? Thanks!!
Not sure about Voicemail problem. Did ATT fix it?
No! It is a problem with the Iphone I have tried to change the carrier file! I have tried several ver's of the carrier file and before I did your update I could change the Voicemail APN but now I can only edit the Cellular Data and MMS APN settings! For some reason the Voicemail APN is gone! Also I have no AT&T logo on my status bar anymore and unders Settings, About, the first line = Network, now says Not Available! IPHONE 3Gs jailbroke on 3.0.1 then applied your firmware via Restore, as Update method always gave me 1600 error! I tried everthing to get it to work and finally did the Restore! Help!! Rod—
You are able to make and receive calls right? I heard about this issue before too, will keep you posted.
Yep Every Thing Works just fine on the Iphone with the exception of Voicemail I can retrieve voice mail from land line or by pressing and holding 1 on the iphone key pad but it gives no notification of a new voice mail and I cannot play the saved voicemail messages from the voice mail screen on the Ipone! AT&T Tells me that I am using What they call Visual voice mail But that is the way it came when I got the phone & rate plan, two months ago! Thanks for your Help!!! Rod

I have a UK Pay as You Go (O2 SIM) phone. Which firmware should I download : Activated or Not Activated ?
Thanks
Does O2 sell iPhones in UK? If yes, then Not Activated. If not, then Activated.
Thanks a lot. O2 do sell Iphones in the UK both under contract and as Pay as You Go. I bought mine direct from Apple and it was locked to an O2 SIM card(on a Pay as You Go Basis).
Use the not activated one!

hi kiran, i was wondering if you could please help me??
im in australia and have 3gs 3.0 whitch was bought from optus and i am using optus sim. im running win xp and itunes 9.0.2.25.
i used blackra1n to jailbreak 3.0, but it didnt work, and now im stuck in recovery mode.
i tried to restore using 3.0, 3.0.1, 3.1.2 ipsw files in both dfu and recovory modes, and itunes says that, "this iphone could not be restored, this device isnt eligable for the requested build". I havent tried 3.1 ipsw though. What should i do to fix this problem? could someone plz give me a hand with a step by step process. plz thankyou.
Hey Kiran its amart again here! Hope everything has been well.
Going to my question…
I just jailbroke iPhone 3G on firmware 3.0.1 and used redsn0w to do the deed with success.
My problem is that when I go to settings and wifi, I let the iPhone scan for Wi-Fi with nothing on the radar. I use my blackberry to search/ scan for Wi-Fi and its finds about 10 people. Pretty much the Wi-Fi isnt working at all. Doesn't find anything. I tried re-restoring and still no success. Please tell me what your verdict or at least a hypothesis is.
Thanks a million in advance Kiran,
amart
Hey! You may try resetting all network settings …
Turn bluetooth off if it is on (Heard conflicting reports on wifi/bluetooth)…
Hope your iPhone is in warranty, Apple will replace it for free!
so if i already had to update to 3.1, (i was stuck in a recovery loop and only way to get out of it was to update to 3.1. ) ,which i assume updated my baseband…..i am still out of luck on a jailbreak with windows…?
3gs, 3.1 xp sp3
Thanks in advance..
Try the DFU / Recovery mode install of this custom firmware. Since the baseband is already updated, it doesn't hurt to try!
hey kiran my 3gs 3.0 is stuck in logo screen after i removed winterboard. im using vodafone india but my fone is origninally frm at&t us so shud i use activated or non activated
It would be activated since the carrier you are using with is not AT&T but Vodafone.
