The end result is far from a fully working Android system.  It’s Android 1.6 with basic features – calls, texts, WiFi but no camera and probably a few Force Closes.  It’s easy to upgrade Android versions once you’ve managed to get to the end of this tutorial so there’s no harm in getting the hard part out of the way now!

Downloads

Here’s a bunch of stuff that you’ll need before you start:

1. IMPORTANT! Jailbroken iPhone 2G
2. VirtualBox (link).  Get the right version Windows/Mac
3. VirtualBox Ubuntu Image (link).  Download number 10, Ubuntu Linux 9.10 codename Karmic Koalax86
4. iPhone Explorer (link).  If you’re on Linux you can use FTP such as FileZilla instead.
5. Android images and sources (link)
6. Patched images (link).  Courtesy of Geekoid.

Getting Android Working!

Well done on getting this far! This is where the fun beings (credits to WinX Blog for these instructions –link)

1. In VirtualBox, the Ubuntu Window, go on Devices > USB Devices and select iPhone (Recovery Mode)
2. In the terminal type (without quotes): ’sudo su’
3. Enter the password: reverse
4. In the terminal type ./loadibec openiboot.img3
5. You’ll see the OpeniBoot screen appear on your iPhone
6. Hold down the power button a couple of seconds (iPhone)
7. The bottom option, openiboot console, will become selected
8. Press Home (iPhone).  You’ll see a bunch of text appear and stop at “Welcome to openiboot”
9. In VirtualBox, the Ubuntu Window, go on Devices > USB Devices and select iPhone (OpeniBoot Mode)

11. Enter the password: reverse
12. You’ll see the same text from the iPhone in the Terminal

14. Wait for it to say Done
15. Type (without quotes) ‘~norbackup.dump:1048576′
16. This creates a backup of your NOR memory – save a copy on USB stick, or email it to yourself or something
17. Type install, press Enter.  When this is done you’ve got openiboot installed on your iPhone.  You’re done!

Finishing Off

What you’ve achieved up til now is Android files on your iPhone, and then installing openiboot so that you have an option to start iPhone OS or Android when you turn on your phone.  Openiboot was necessary because that’s the only way right now that you can boot into Android.  Here’s how to finish off and get into Android:

1. If you still have Terminal open with the oibc still running, just type ‘reboot’, press Enter and skip to step 3
2. If you don’t have Terminal open, disconnect your phone, turn it off and back on
3. When openiboot appears press Power button to switch to openiboot console (bottom option)
4. Hold down the Home button
5. Android will start to boot, but it might take a while

Good Night

I think this guide is plenty enough to help you get Android on your iPhone.  As mentioned, it’s not the full OS yet, but hopefully we’ll see a lot more devs contributing and a lot of advancement of this project.  It’s gotten quite late and I woke up really early so I’m heading off to bed.  Feel free to mention any issues in the comments and I’ll try to help out tomorrow.  I’ll also get some screenshots and videos up tomorrow too!
