OK if you have an iPhone with bootloader 3.9 (OTB 1.1.1 or lower) continue reading. If your iPhone came with 1.1.2 or 1.1.3 firmware installed OTB DO NOT DO THIS!

This will update your Baseband so that you have the latest modem on your iPhone. It means you can use Google Locate without the need to run any additional 3rd party apps. The best part is you keep all your apps, customizations and jailbreak and after following the second tutorial you will alo be unlocked.

FYI - make sure you read and follow every step (including putting the iPhone into Airplane mode)

AND these instructions assume and tell you that you need firmware 1.1.3. DON'T do this if you have not or are not going to upgrade to 1.1.3 first!

First of all follow this post: Upgrade Baseband Tutorial

Then follow this post: Unlock with AnySim 1.3 Tutorial

I now have 1.1.3 Firmware, 04.03.13_G Baseband, Bootloader 3.9, Unlocked and jailbroken. (which basically means Google Loacte works)

Hi there how do I know which version of the bootloader I am using? My phone tells me that I'm on baseband 04.03.13_G I recently upgraded my OTB 1.0.2 to 1.1.3 having done the 1.1.1 and 1.1.2 steps. The phone worked fine for a couple of weeks then died on me.

To find your bootloader version install bbinfo via installer. Run it and it will tell you your bootloader version. If you are on baseband version 04.03.13_G you shouldn't need to do this as it upgrades previous basebands to that.

How did you upgrade to 1.1.3 and baseband 04.03.13_G? Did you use the Dev teams soft upgrade?

When you it has died on you, in what way? It doesn't switch on? you can't get service? It always goes to restore mode?

Please give us a bit more info and we (GZ Users) may be able to help

Yep used the Dev software upgrade..when I say died I mean it went back to the restore screen, with the cable end and iTunes logo on screen. I have since restored to 1.1.1 but AnySim 1.1 will not work and the upgrade to 1.1.2 does not work so I'm stuck with an iPhone without the phone function..

Any help would greatly be appreciated.

OK, If I understand you correctly you have:

OTB: 1.0.2
Bootloader: 3.9
Current Firmware: 1.1.1
Baseband: 04.03.13_G
Jailbroken
SIM - Locked
WiFi Working

Is this correct? If so keep reading, if not please correct what I have wrong

If so follow the guide below to downgrade you baseband. Once you have completed the guide below you can unlock and stay at 1.1.1 or you can install OktoPrep and update to 1.1.2 then update 1.1.3. Head over to iclarified.com They have heaps of tutorials.

Step One
Press to select Settings on your Springboard.

Step Two
Press to select General from the Settings Menu.

Step Three
Press to select Auto-Lock from the General Menu.

Step Four
Press to select Never from the list of Auto-Lock times!

Step Five
Press the Home button to return to your Springboard. Now press the Installer icon to launch Installer app.

Step Six
Press the Sources tab at the bottom of the screen.

Step Seven
Press the Edit button at the top right of the screen.

Step Eight
Press the Add button at the top left of the screen.

Step Nine
Enter http://i.unlock.no as your new source and press the large OK button.

Step Ten
Press the Done button at the top right of the screen.

Step Eleven
Press the Install tab at the bottom of the screen.

Step Twelve
Press to select Unlocking Tools from the Category list.

Step Thirteen
Press to select Baseband Downgrader from the list of Packages.

Step Fourteen
Press the Install button at the top right of the screen.

Step Fifteen
Press the large Install button that appears at the bottom of the screen.

Step Sixteen
A Notice will appear asking you to make sure that Auto-Lock is set to Never. Since we already did this we can press the large OK button.

Step Seventeen
Once completed you will receive Notice that your Baseband is now downgraded! Press the large OK button.

OK so the latest update is..restored the phone to 1.1.1, ran the jailbreak, and loaded the installer, then did the baseband downgrade as directed, that went ok, then ran anySIM and that ran fine......but...the phone is still showing "no service" or northing at all in the network line.. Should I have run the 1.1.1 restore again after the baseband downgrade? This is so frustrating but fun at the same time..

sackmaster: Should I have run the 1.1.1 restore again after the baseband downgrade?

Yes, after the downgrade it should have told you to do that. One thing you should always always do is follow what it tells you to do. If it tells you to "jump around and make a lot of sound" then do it!

Cool, I am glad it has worked for you.

To get to 1.1.2 follow this guide.

once there you will need to unlock following this guide

once on 1.1.2 follow this guide to get to 1.1.3

and then follow the guides at the start of this Geekzone thread to update the firmware to 04.03.13_G and Unlock.

This should now pretty much sort out anyone on 1.1.1 who wants to get to either 1.1.2 or 1.1.3

NOTE: Sorry but I have to point this out again. Linka, Geekzone and I won't and don't take ANY responsibility if anyone bricks their iPhones whilst following any of these methods or guides.

You will need to restore to 1.1.1 and then follow the guides to jalbreak and then follow the guide above to get your baseband back to 04.02.13_G. Once you have done this you can unlock.

I can but I need more information from you.

OTB model? 1.0.2, 1.1.1, 1.1.2 or 1.1.3
Current baseband before things went wrong
Your Operating system on your computer

Also you need to use real English, I hate text language.

Does itunes recognise it? I reccomend you get iTunes 7.5 as well.

If it does you are going to need to do a shift restore and restore to 1.1.1. (Download the 1.1.1 frmware then hold the shift button and press restore in itunes. It will ask you for the location of the file you wish to restore from. Choose the file you downloaded) I will not link to the firmware, you will have to search for it - try modmyifone of iclarified.

It may take a couple of tries to get rid of the green screen. Also if iTunes doesn't recognise it you will need to put it into DFU mode by holding down the home button and the power button on the iPhone until it reeboots and shows the iTunes logo and cable image. Then when you connect it should recognise it.

Once you have done an iTunes restore to 1.1.1 you will probably get an error and the iPhone will be in DFU mode. Connect it to ibrickr and boot the phone you should then get the activate/emergency call screen.

Once you have restored to 1.1.1 locked and unjailbroken let me know.
