Been having trouble unlocking your iPhone 3G with yellowsn0w? Follow this guide!
Note: This IS beta software, there is no guarantee this will work. Use at your own risk!
First is first, Jailbreak your iPhone (If your iPhone is already jailbroken you may skip steps 1-7)
- Install firmware 2.2 if you didn’t already (Download it from our iPhone Downloads section: Here
- Download QuickPwn to jailbreak your iPhone 3G (Again, download it from our iPhone Downloads : Here for Mac
Here for Windows - Pick the desired device, the iPhone 3G of course
- Use the latest firmware version to pwn your iPhone 3G (Download it from our iPhone Downloads section – Link above) If you just updated your phone or updated your phone on the computer you are running quickpwn on, you probably won’t have to download the firmware.
- Quickpwn will rebuild the IPSW
- Quickpwn will send the firmware
- Jailbreaking iPhone 3G was Successful with Quickpwn
- Open Cydia or Installer and enter the yellowsn0w repo URL (Do NOT enter these URLs into your browser)
- Cydia will download the repo packages
- Confirm you want to install yellowsn0w
- Cydia will download yellowsn0w and install it for you
- Turn off the iPhone and install your third party SIM.
- Turn on the phone. Wait until your carrier pops up. If it doesn’t, take the SIM out and reinstall it.
Now that you jailbroke the iPhone 3G, it’s time to unlock the iPhone 3G
For Cydia enter: http://apt9.yellowsn0w.com/
For Installer enter: http://i.yellowsn0w.com/
Note: If you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch in Settings.

good work nerds
hey any one can tell me if i can unlock my 2.11.07 iphone bcoz i dnt wana update to 2.28.00 kuz i wil lose all my apps then??
plz help
No, this will only work on the 2.28.00 baseband on the iPhone 3G
didn’t work or get any signal
I have this problem is there a fix??
so is there any way i can just update my baseband??
i got the new firmware 2.2
did the restore five times tell now and done all the steps as written but didn’t work with me
can someone write down if this working or not
remove your sim card
Just tried unlocking my iphone, even though I have AT&T currently, but I am experiencing my service cutting in and out.
I am experiencing the same.
When I remove the Zappa app, my service stays up. I’m gonna wait till it isn’t a beta anymore.
Damn the carrier doesen’t pop up. Any suggestions ?
I dont get the carrier and i get no service but it doesnt say “SIM Failure” any help plz and i did turn off the 3g because i am tryin to use my T-Mobile
Not working for me. I followed the steps correctly but it gives me a sim failure. I have an iphone 3g under O2 UK. Any suggestions?
Never mind my previous post. Its working. This is what I did. I inserted the O2 sim which it detects cause the phone is locked under O2 network. After it detected the network I went to airplane mode and pulled out the sim and put my sim from telenor. I deactivated airplane mode and it got full network in 10 seconds. Edge is working too. I cannot confirm 3G because it is not supported by my sim.
The trick is I had to do this several times before this happened…more then 10 times actually. I dont know if I did anything by accident but its working right now. I used yellowsnow ver 0.9.4
Thanks dev team. You guys are unstoppable and super awesome.
I think its a good idea to turn off 3g if your sim doesnt support it cause I lost network as soon as I did. But then again I am no expert.
i worked for me yayyyyyy guys if u have 2 iphones or have a friend that owns the 2g or 1g unlocked just put ur sim in his phone and wait till the carrier shows up then put it bak in the 3g it should work i did it to mine. at first i thought i had the same problem as u guys did then i just started messing around and poof my 3g is unlocked
didnt work for me….at the end the part i supost change the simcard…when i change dont appear nothing….. trying to change optimus to tmn can u help me guys?
really fu«ks me up… i did everything rigth….after i change de simcard just apear the signal (just one bar) but dont appeart the name of the operator.
never mind…..i did it….reintall like 200 times….
XD changing sims….bah….now the fucked up thing its the contacts….
dev team! u guys….are brilliants!
fkn fag stop talking to yourself >__>”
habib123, calm down.
Well done dev team… would gladley of paid to have access to yellowsn0w….
First pawnage went without a hitch, however after installing yellowsn0w the iphone did not unlock to sim used. I repeated the process again, nothing different and it worked perfectly.
Nice one!! Happy new year ya all…
Cheers

Ireland, 3G on meteor…. :-)
Sound, good to hear, because I’m in Ireland and on Meteor too, getting an iPhone 3G and all these forums talk about American networks and I was bricking it in case it wouldn’t work with meteor for whatever reason! Is it easy enough to do yeah?
no leave ur 3g on and switch sims with an tmobile phone wile ur 3g is still on and wen the signal loads on the tmobile phone remove it and put it back in ur 3g it should work i got mine working. my phone dosent read it wen it powers down i have to remove it n put it in a nother fone then put it bak in my 3g wait a minute and it loads. o make sure the 3g switch is off and data roaming is on
It works. The signal for T-mobile is ok. But when I make a call, the signal was dropped. This is a beta version. I hope they will release a full vrsion. Anyway thanks for your hardly work.
Did this Works for ipod touch 2g too ?
please tell me it does. hard to believe that the ipod touch 2g 2.2 firmware is the ONLY device that cant be jailbroken.
I installed the 2.2 upgrade for iPhone3G and then jailbroke it with QuickPwn (windows XP). I also ran the yellowsn0w install, all this done without a problem. But now I see just one bar in the signal strength and the carrier name does not popup. I am using a Vodafone connection in India. Any suggestions?
Once jailbroken, and yellowsnow applied. I found once new sim inserted goto settings and switch on/off airplane mode (few seconds)phone will begin searching… worked like this for both my iphones…
worked for me twice…. great job guys!!
Buttons
I tried this but everytime i get a sim failure pop up and an “Invalid sim” where the carrier should be. Help?
hey anyone know if you can get 3g speeds with t-mobile or any other carrier or is it just 2g service for all of them ??
thanks in advance for your responses …. redrum801
thankx bro…. i was struggling past month.. after updating my phone to 2.2 atlast i got to use my sim in armenia… thanx a lot bro….. keep doing the gr8 job…
great job dev.team, it’s work.. so far i can use my iphone w/out any problem..
i cant get my iphone to reconnect in recovery mode(the first step in quick pwn) … I mean it does everything else fine connects and finds firmware 2.2, then tries to reconnect in recovery mode(before the steps where it tells you to hold down buttons and all that) and it just stays there for ever and my goes into recovery mode but quick pwn wont pick it up? any ideas
If you are on Mac OS X 10.5.6
Re enable DFU mode on it
http://www.iphone-hacks.com/2008/12/19/re-enable-dfu-mode-in-mac-os-x-1056/
Works LiKe a ChaRM!!!!! UsEd the installer!! and in few mins It unocked!!! and running tmobile as i type plus Wifi works great!!
Can someone help this idiot. Do I need 2 sims to do this? if so, where would one obtain an additional sim? I am really interested in jail braking my phone but seeing that I have never done this before, and without seeing it done, I am confused as to what I will need to have _before_ I start this process.
Would anyone mind helping me here?
Thanks

Hey I have a quick question… I called apple a couple of days asking if there was any way to unlock the iphone since I am traveling to a country were iphone is available and wanted to use my iphone with that company. AT APPLE they told me I could run a UNAUTHORIZED UNLOCK (the rep told me this with a rep from AT&T on the line too which started an argument between the 2 of them) and that I WILL NOT LOOSE MY WARRANTY unless my iphone gets broken and the reason for the iphone to be broken was part of the unlocking process.
SO, if I unlock my iphone, and in case of having a problem, can I restore the iphone to factory settings so Apple wouldn’t know the iphone was unlocked???
Thanks
FranNyc
yes, you uninstall yellowsn0w and you restore your iphone.
Sweet! works great, keep up the good work!!!
Yellowsn0w 0.9 to 0.9.5 did’n work on my iphone 3g but after upgrading yellowsn0w to 0.9.6 the software worked perfectlly after a reboot.
Thanks for this software.
Working great.
Except wifi connection how can i install Yellowsn0w.
tnx
u need a way to connect to internet through your phone….
Hi guys, I am having problems even jailbreaking the phone which is totally baffling. I have been waiting for this unlock for several months now knowing that I’ll be travelling out of the US for a total of 2 months since X’mas. Naturally when it was finally released, I was so thrilled & downloaded the software. Of course, it didn’t work & didn’t bother trying to remove & reinstall the SIM card since after skimming thru the instructions (oh yes, I had already jailbroken my phone with NO PROBLEMS just one week after buying it in September), I realized I had to update it to 2.2, which I had been avoiding since I had heard my phone will no longer be jailbroken. I really didn’t feel like reinstalling everything again.
Well, I didn’t think anything of it since I’ve jailbroken many of my friend’s phones & as you guys know, that takes less than 7 minutes maybe less.
The first time I did it, nothing happened, no Cydia or Installer icons & when I tried doing a restore, I got this weird cartoon dude with what appeared to be Russian writing coming out of his mouth. Then it was stuck in that state for at least an hour!
Fine, it was evident it stalled so I decided to restore the entire phone to factory settings.
My problem is I have been trying to jailbreak for the past 3 days now & I know most of it is working since if I power on, I see the kernel logo instead of the standard apple. Also, I if I move my icons around (there isn’t enough to fill up one page), I notice that there are 2 existing pages. If I flip to the second page, it is blank. Which means ’something’ is there. I just don’t see the Cydia or Installer icons! Reinstalled it several times including removing the kernel (kernel does remove so something IS going thru), but no other icons appear.
No icons, means no downloading of the unlocking software or any other 3rd party software for that matter.
Sorry for the long explanation but I wanted to be clear on the steps I took so I get a clearer solution to this problem.
Thanks heaps. I really need my phone to work here in Singapore as I will still be here till March 1st! HELP!

Thank you for this very informative and easy to follow guide.
Regards Silver
I’m getting a second-hand iPhone 3G, so when it says in the instructions above to install firmware 2.2 and also to download quickpwn, should I do it on the computer of the guy I’m getting it from? Also, when should I put my own simcard in the iPhone? Like, before I do any of the steps above or after a certain point? Thanks in advance for the help, just I’m not very technologically advanced, haha! If it matters, I use a Mac and the guy I’m getting th Iphone from uses one too?
Cheers folks!
