Even though iOS 5 won't be released officially until October 13th, you can install the final version right now even if you're not a developer. Thanks to some anonymous public postings of the software update files, you can update right now. Here's how.
Special thanks to Locker Gnome for discovering this.
First things first, back up your iDevice with iTunes in case of a problem. There have been a few reported issues with this process. We've run into them ourselves. We tested this with Whitson's 4G iPod Touch, and it didn't work initially but we got it to function after restoring iOS 4.3.5 and trying the iOS 5 upgrade on a different computer. The point is, you're going to need to restore regardless so back up. Once that's done, grab the relevant software update at one of the following URLs:
- iPhone 4 (GSM)
- iPhone 4 (CDMA)
- iPhone 3GS
- iPad 2 (Wi-Fi)
- iPad (Wi-Fi + 3G GSM)
- iPad (Wi-Fi + 3G CDMA)
- iPad (Wi-Fi)
- iPod touch (3G)
- iPod touch (4G)
If your device isn't listed above that means the software update file (IPSW) wasn't posted or your device isn't compatible. The only notable option missing, however, is the iPad 2 with 3G. Once you've got the file, follow these easy steps:
- Open up the DMG file (Windows users will need a tool like 7-Zip to do this), and find the IPSW file for your device. Drag it to the desktop, or a folder of your choosing.
- Open iTunes and connect your iDevice to your computer.
- If your device isn't automatically selected in iTunes, select it and go to the "Summary" tab.
- Hold down the option key on a Mac or the shift key on Windows and click the Restore button. Browse to the IPSW file you download it, select it, and wait for the update to finish.
- If necessary, restore your device from backup and sync with iTunes.
That's all you have to do. It shouldn't take to long and you'll be up and running with iOS 5 right away.
