EDIT: This is intended to show you the experience. Here is the guide to unlock iPhone 1.1.2.
Newly bought U.S. and U.K iPhone with 4.6 bootloader will not work.
A lot of people want to know what will unlock iPhone 1.1.1 happen when they upgrade to iPhone 1.1.2. Since some jailbreak and unlock new software news is there. Here is how I “scarifies” my iPhone 1.1.1.
This is intended to be a demo to show you the steps I did. We do not intended to encourage to upgrade your iPhone.
The victim iPhone is in 1.1.1, unlocked with anySIM 1.1.1. It also installed with lots of 3rd party softwares.
This is a live blog. Please click the following “Read More” link and keep refreshing.
Sorry that I am a Mac guy. I do use Windows, but this time I decided to use Mac.
This guide is done under Mac OS X Leopard 10.5, iNdependence 1.3 beta 2 and iTunes 7.5. The iPhone is bought in U.S. Huston.
Stage 1: Restore and upgrade to iPhone 1.1.2
Step 1. I downloaded iPhone 1.1.2 restore firmware from Apple.com. Than I go to restore it by using the Option + click method.
Step 2. Things are going pretty well. And now the iPhone is in 1.1.2. It is an iBrick and cannot be used for anything.
Step 3. It looks like the iPhone cannot be using the *#307# technique to bring up the contacts. So I restore it to iPhone 1.1.1 by using the Option + click method in iTunes 7.5. See whether it is reversible.
Stage 2: Back to iPhone 1.1.1 and baseband still in 1.1.2.
Step 4. Now the iPhone come back to iPhone 1.1.1. Error 1015 at the end. The baseband is still in 1.1.2, which is 04.02.13_G.
Step 5. Just uploaded the anySIM 1.2 by Elite Team. It seems running. But in the middle, it hangs and go back to springboard. Looks like the iPhone is bricked. OMG.
Step 6. I uploaded the anySIM 1.1.1 into my iPhone. And then replace the existing content with the on from Elite Team. See whether it works for this time. Okay. Now erasing my baseband now.
Step 7. The iPhone is still locked. Apparently anySIM 1.2 by elite team does not work for iPhone 1.1.1 at 1.1.2 baseband 04.02.13_G.
Stage 3: Going back to iPhone 1.0.2
Step 8. Since the anySIM 1.2 cannot unlock my 04.02.13_G at iPhone 1.1.1. I will now go back to iPhone 1.0.2 and try to virgin the baseband.
Step 9. I used iNdependence to help me to get into DFU Mode. And then I closed it and start the iTunes. Also used the Option + Click method to select iPhone 1.0.2 firmware.
Step 10. Weird things happened! My iPhone 1.0.2 now unlocked with 04.02.13_G baseband (which is from 1.1.2). Look.
Step 11. Now I will try to upgrade my iPhone to 1.1.1 through iNdependence. Click the Pre 1.1.1 Upgrade.
Step 12. Upgraded. And Error 1015 at the end like step 4. It holds at the recovery mode and cannot get rid of it using iNdependence. I cannot slide for emergency so cannot try to jailbreak using jailbreakme.com
Step 13. Restore it again to iPhone 1.0.2 now. Now activating and will soon flash the baseband.
Step 14. Now ierase the baseband. I need to put the new secpack 04.02.13_G from iPhone Dev Team to make it work. And now. The baseband finally erased. Here is the stuff that I used for ierase the baseband
Step 15. Now virgin the iPhone 1.0.2 so that it can be unlocked again after upgrading to iPhone 1.1.1.
Step 16. Upgraded to iPhone 1.1.1 again. Now unlocking again with anySIM 1.1.1.
Step 17. Things are going back to normal. And happy iPhone at 1.1.1.
Let’s sit back and don’t upgrade your iPhone to 1.1.2 yet. Wait Wait and Wait.

Hmmm.. Looks like people are updating their iPhone 1.1.2 to take some risk. I will modify this guide and write a new guide for making iPhone 1.1.2 work by downgrading. Stay Tuned.

Just got an OTB1.1.2 and was able to downgrade it to 1.1.1 and jailbreak it. YouTube and Safari work thru Wi-Fi. Have not been able to use AnySim. Modem FW is still 04.02.13_G.
Do you know of any latest developments regarding the baseband downgrade of a 04.02.13_G to 04.01.13_G?
Thanks!

Thanks
Waldo,
Take a look of iPhone ultimate guide page.
Is there anybody on this forum who was able to downgrade the BB from 04.02.13_G to 04.01.13_G on a 1.1.1 firmware Iphone. I was able to install all levels of firmware but was absolutely unable to get the BaseBand changed to a lower level.
I´m wondering if anybody was able to do it !!
Thanx Ed
