How to Upgrade, Jailbreak and Unlock Iphone v3.0
Sync- make sure you sync your Iphone, as the 3.0 firmware will delete all the data and apps on your phone. After the upgrade you can re-sync the data and apps back to the Iphone.
Note: Apps added with Cydia or Installer will need to be reinstalled manually.
Download- You will need the following
Itunes 8.2
Iphone V3.0 Firmware (download through Itunes 8.2)
redsn0w (available at blog.iphone-dev.org)
Install- You will be prompted to install the V3.0 update, click on update and wait for the process to complete.
While you are waiting, install redsn0w (the 3.0 jailbreak) by Extracting redsn0w-win_0.7 to C:
Jailbreak- Once your phone has been updated; it’s time for the Jailbreak. Locate the 3.0 firmware update; the updates are stored in C:Documents and SettingsUsernameApplication DataApple ComputeriTunesiPhone Software Updates. Copy the file to c:redsn0w-win_0.7
Take the firmware file and drop it onto redsn0w.exe
Check the boxes to install CYDIA and ICY.
Wait for a message to come up saying please connect your iPhone into DFU mode. Then connect your iPhone to the computer if you haven’t already done so, and hold down
the Power and Home buttons for 10 sec. (If the apple screen comes up you have gone too far)
Then let go of the Power but keep holding onto the Home button. Hold it for at least 30 sec or until it reconnects to the computer.
Go to the Command Prompt window (from the start menu, select run and type cmd and and press enter.) When the command window comes up, press enter.
Unlock- now that you have updated your firmware and jailbroke your phone, it’s time for the Unlock.
Run Cydia or Icy
add the repo repo666.ultrasn0w.com to Cydia or icy
Search for ‘ultrasn0w’ in cydia or ICY and install, then reboot the Iphone.
Final Steps- Now that the IPHONE is updated, jailbroken and unlocked, it’s time to resync the phone to Itunes. You may want to review the sync options in Itunes to insure your apps and data will be synced the way you’d like.
After Syncing your data and apps back to the Iphone, check the APP Store application for updates, as many apps have been updated to work with 3.0.
If you had any Cydia applications, you can reinstall them using Cydia or ICY.
Finally, enjoy!
