The above list also represents all supported iDevices by sn0wbreeze.
Run sn0wbreeze, click OK, click Close Credits and click Next
Click Browse and locate the official 4.1 IPSW for your iDevice
Select your IPSW and click Open
sn0wbreeze identifies your iDevice base from the iPSW you selected. Once it's done, click Next
Select Expert Mode then click Next
Select General then click Next
Choose your preferences then click Next Basically, the 3 options on the left are for iPhone 3G and iPod touch 2G users only because these features are already available (as a default) on newer iDevices such as the iPhone 4. Activating is for iPhone users only. Lastly, SSH is something that let's you access the files and folders on your iDevice. You don't wanna mess with this if it's new to you.
Click Next again
Click Build IPSW then click Next
Wait until sn0wbreeze finishes creating your custome IPSW. Click OK once it says Done You will find the new custom IPSW saved on your Desktop. The filename should contain the word "sn0wbreeze_" on it so there's no chance that you get it confused with the official IPSW from Apple. Watch this video...
Plug in/connect your iDevice to your PC (computer)
Turn your iDevice OFF and prepare to put it to DFU mode You can also opt to close sn0wbreeze and use iReb instead. Download iReb HERE.
Click on Start.
Press and hold POWER and HOME buttons for 10 seconds
Release POWER but keep holding the HOME button for another 30 seconds
Release HOME button once sn0wbreeze says Running iReb...
After that it will tell you: Your device is now in a PWNED DFU state. Just click OK
Then iTunes will detect your device in recovery mode. Click OK again
On your computer's keyboard, press and hold SHIFT before you click on Restore (on iTunes)
Locate the custom IPSW you created using sn0wbreeze
Select the correct IPSW and click Open
Click Restore and that's the final step. All you need to do now is wait. After the restore is done, iTunes will ask you to set up your iDevice. In case you come across any kind of error, use iReb to put your iDevice on a PWNED DFU state. Download it HERE.
Once that is complete, you will find Cydia on the 2nd page of your iDevice's homescreen.
And for iPhone users, next thing to do is to UNLOCK. CLICK HERE to learn how.
Hi i write hear because i have a big problems!
I used this guide an everything was perfect until i decided to restore my iphone 3g with itunes. i had 1015 error so i tried to instal redsn0w again but alvays when i finsh the instalation proces i get screet to conect my iphone to itunes and the same thing again and again.
How should i restore my iphone, is there any way to do that ?? please i just bought my phone one weak ago!
All Skype versions work perfectly for the iPhone 3G, unless you did some buggy jailbreak. Go to the App Store app on your iPhone and download Skype from there.
If you're really having problem making it work, I would guess did a jailbreak using earlier revisions of redsn0w 0.9.7.. that's a little buggy release of redsn0w. To fix it, restore & re-do the jailbreak using a other tools such as sn0wbreeze.
You can certainly jailbreak, but you cannot unlock as of yet. It doesn;t matter if you downgrade the 4.1 firmware, that may help you jailbreak but it is the Modem Firmware or Baseband that matters. Your baseband upgrade camme with the 4.1 update. Since you are at 05.14.02, you cannot unlock as of now, period. You cannot downgrade the baseband on a 3GS, so jailbreak using Limera1n or Greenp0ison, but you need to wait for a new version of Ultrasn0w in order to unlock for anything other than AT&T.
Dont worry though, my sources tell me that the unlock is on it's way to be released.
