iPhone OS 3.0 GM Seed installation steps via iTunes & XCode

I couldn’t find these instructions in the iPhone Development portal, so I figured i’d share them with you here.  Once you download the appropriate GM seed, here’s how it’s done (I’m assuming you’ve already designated your phone as a dev device.):

1. Make sure…
   1. to downloaded correct GM Seed for your iPhone (1st Gen or 3G).
   2. that your system and version of iTunes meet the requirements: 

      “You must be running Mac OS X v10.5.7 and iTunes 8.2 in order to install iPhone SDK 3.0 GM Seed and iPhone OS 3.0 GM Seed.”

      “You must be running Mac OS X Snow Leopard Final Developer Preview (Build 10A380) and iTunes 8.2 in order to install the iPhone SDK 3.0 GM Seed for Snow Leopard and iPhone OS 3.0 GM Seed.”

2. Extract the firmware .ipsw to a folder.
3. Connect the iPhone to your computer.
4. Back up your phone!
5. Open iTunes and click Restore while holding the Shift key (for Windows) or Option key (for Mac).
6. Locate or browse to the firmware IPSW.
7. Wait for iTunes to unpackage and install the firmware.

OR you can just use Xcode…

1. Back up your phone!
2. Open Xcode
3. Open the Organizer (Window -> Organizer)
4. Flip the software version to “Choose…”
5. Select the GM Seed ipsw file
6. You should  see a message that says something like “These changes will take effect when you restore you phone”
7. Click on the “Restore iPhone” button and watch the magic happen.

By backing up your phone ahead of time, you’ll be able to tell iTunes to put all of your crap back on it when the process is done.  It’ll even try to preserve icon locations

Happy hacking.
