This Guide is For iPhone 3G
These are instructions on how to Restore And jailbreak your iPhone 3G on the 4.2.1 With Custom Firmware (if You Already Have 6.15 Baseband)
IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.
1-Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).
2-There are reports that 06.15 may disable your GPS. The iPhone Dev-Team is currently working on a fix.
Don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.
