Step by Step Guide to Unlock your iPhone 3G
I wrote a post on how you can unlock/jailbreak your iPhone 2.2 Firmware. I have just discovered that you can now unlock your iPhone 3G using this application called YellownOw as well.
YellownOw is an easy to use app which runs as a command line application once your iPhone 3G is jailbroken. Before you get started make sure that your iPhone 3G is up to date with latest iPhone OS from Apple.
Thanks to hackint0sh for providing step by step installation method to unlock iPhone 3G . It’s been tested with different SIM cards and it works just great.
1. Recover your iPhone to 2.2 with bb 2.28.00 after ready close iTunes. Dont sync, activate or nothing just close it.
2. Quickpwn it with installer and cydia installed
3. When phone is ready, connect to Wi-fi, go to cydia, when opened for the first time ignore the update for Cydia and install first mobileterminal and after sbsettings from Cydia.
4. Turn off data roaming and 3g connection from settings.
5. Install yellowsn0w from installer after adding the source http://i.yellowsn0w.com.
5. Slide your finger from top left to right on the screen to get sbsettings open
6. Press power button from sbsettings and from the popup restart button.
7. When phone is reset wait for 20-30 secs and go to mobile terminal
8. Go to terminal
- type yellowsn0w -c
- type yellowsn0w -q
- airplane mode on
- airplane mode off
if you get “open: Recource busy” just repeat the command where you got it from. If command yellowsn0w -q keeps loading for more than 20sec and your terminal looks similar to the picture below, move to next step

9. Go to setting, turn airplane mode on wait 10 secs and it should start searching for the network, it should find the network and everything must be functional by now.
If it still show the four dots for the signal repeat the steps 8 and 9 but first exit mobile terminal totaly by holding down the home button until it closes totally. If that doesnt work either use compination
- go to terminal
- type yellowsn0w -c
- type yellowsn0w -r
- type yellowsn0w -q
- airplane mode on
- airplane mode off .
That’s how you get it working for 99% sure. i tried it in 3 different iPhones one from Finland one from Germany and one from UK. UK and German wasn’t working in the first. Until now many has gotten it to work only by this method.
I got it to work by the usual phone on and phone off.
So only thing you have to actually do is to install yellowsn0w from installer not from Cydia. and after every time the phone boots, wait 30 secs and make the commands with mobile terminal (step 8)-> and airplane on off, if doesnt work repeat the step 8 and again airplane on off.
If you lose network use this combination and you’ll get network back without reseting the phone
- go to terminal
- type yellowsn0w -c
- type yellowsn0w -r
- type yellowsn0w -q
- airplane mode on
- airplane mode off
Let us know if it works for you.
