Downgrade iPhone 1.1.2 to 1.1.1 and Unlock from Encript on Vimeo.

When I first unlocked my phone I have never used an iPhone before so I was hesitant on what I should do or how I should go about doing it. Here is a video representation of some information I have gathered over the internet in addition to some simple steps. ***Windows Only***

1. If you have an iPhone which is already on 1.1.2 and was not purchased out of the box with that firmware then we can proceed with the downgrading process. If you are already have 1.1.1 then you can skip the downgrade procedure and go to jailbreakme.com solution and go to the following step.
2. Hook up your iPhone to your computer and make sure your computer recognizes it and iTunes can see it. Once you seen your phone in iTunes click on the SHIFT button and hold it then click on restore. A dialog box will pop up for you to browse to the firmware file. locate the firmware named “iPhone1,1_1.1.1_3A109a_Restore” and then click open. Get it here. It is now in the process of downgrading your phone don’t touch your phone just let it continue. When its complete you will receive an error message 1015. Don’t panic like I did this is perfectly fine.
3. This step may not be necessary however your phone may not wake up after the downgrade. To force it to wake up and take you to the activation screen you will need a program called “AppTappInstaller” this is just to wake the phone up.
4. Once the phone is on the activation screen you will need to enter some information into contacts but in order to get there you have to type *#307# your phone will ring dont worry no one is calling you. When the phone rings delete the number’s you typed and type 0 and answer. The phone will ring again just then place the call on hold. When the phone rings this time decline it and it will take you to where you can enter contact information.
5. When in contacts enter the following new urls “prefs:” and “jailbreakme.com”.
6. This next step your going to need to add your wifi settings. So clicking on pref: will take you to your preferences where you can add your wifi information. Also go in and change sleep to NEVER this is important. When that is completed then you can go to the next step.
7. You will have to enter the code again to get back into the contacts. Just type 0 answer hold and then decline. This time you will click on jailbreakme.com which will connect you to the internet so you can exploit your phone. When you do this it will kick you back the the activation screen and and automatically boot your phone.
8. Now this may not happen with you but it sure happened to me. The phone would not reboot on its own. So I had to keep trying till i got it. To save you some time here is what I did to kick start the exploit in to working. Plugging the iPhone into a power source or a different computer made it go. If that doesnt work somehow by putting the iphone in landscape mode in safari did the trick.
9. Now that the phone is Jailbroken you should see installer.app on your phone. Go ahead and launch installer.app and browse to network where you will find OpenSSH. Go ahead and install that. Next you will install anySIM1.2.1u
10. You will need to connect to you iphone and transfer the anysim manually. Use WinSCP or any FTP program you prefer. Check to see what your iphone IP address is. You can see under settings, general, wifi, just click the blue arrow near your network. One you have the ip address which is your user name you will need the password which is “alpine”. Now take the anySIM1.2u file and extract the folder and rename the folder to anySIM.app. upload this to your iphone’s applications folder. Once its uploaded go onto the folder and find the file named anySIM right click on it and change the file permissions to 0755 this will allow read write execute on this file.
11. Almost done. Lets restart your phone you should now see the anySIM file. Go ahead and change your sim to the other carrier. Launch the program and let it begin its thing. Great now that its complete lets move on.
12. In installer.app lets go to tweaks 1.1.1 and then to oktoprep. This will allow us to install 1.1.2 from iTunes. Your phone wont show unlocked yet until we upgrade. Connect your phone to iTunes and make sure it reads it. You will need to download 1.1.2 here. In iTunes hold SHIFT and upgrade then browse to the file named iPhone1,1_1.1.2_3B48b_Restore.
13. Lastly we will jailbrake your fresh new 1.1.2 and be done. Grab the file here. click on the windows file check install ssh then jailbreak and let it do its thing. Your phone will restart a few times and thats it all done. I personally will stay at this fimware for a while till 1.1.3 official apps begin to come out. Also because the BSD Subsystem kills my battery.
