Monday’s keynote declared the 21st as the day iOS 4.0 will be publicly available to owners of an iPhone 3G, iPhone 3GS, iPod Touch 2nd gen, and iPod Touch 3rd gen.  iPod Touch users will be relieved to know the update won’t cost them a dime.  The best news of all?  The developer GM seed is reportedly working without UDID activation.   So let’s get to it, eh?

Here’s what you need:

  • iPhone 3G, iPhone 3GS, iPod Touch 2nd Gen, or iPod Touch 3rd Gen
  • iTunes 9.2 Beta — Currently Mac ONLY (Sorry Windows users)
  • iOS 4 GM IPSW for your corresponding device


Head on over to GumballTech for a list of several download links to the iTunes 9.2 Beta (69.62MB).  While that’s downloading, pick up the iOS 4 GM firmware for your iDevice just below the iTunes Beta links.  Double check to make sure you’ve got the correct firmware for your device while it’s downloading.  Each device firmware starts with the device’s name.

  • iPhone 3GS reads iPhone2,1
  • iPhone 3G reads iPhone1,2
  • iPod Touch 3rd Gen reads iPod3,1
  • iPod Touch 2nd Gen reads iPod2,1

Triple check it.  Are you sure you’ve got the right one?  Good.  Install iTunes 9.2 Beta on your Mac, open it once installed, and plug in your iDevice.  Locate your Device in the iTunes left hand column, right click and choose “Back Up”.  You NEED to do this to prevent any loss of data incase something were to go wrong.  Once your device firmware is finished downloading, hold ALT and click “Restore” in iTunes.  Find the IPSW and let your device update.  Once booted, click “Restore” to return all data to your iDevice.


You’re running iOS 4.0 way before its release, which might boost the value if you’re looking to sell it on eBay ahead of iPhone 4.  Remember to upgrade at your own risk but don’t forget to drop us a line to let us know how it went!!
