Download the iOS 4 GM (Mac Required!)

June 11th, 2010

The official iOS 4 is coming to iTunes in less than 2 weeks- and if you’re anything like me, you may be anxious to get your hands on it now. If so, I’ve got you taken care of.

Unlike previous iOS 4 Betas, this GM does not require your iPhone UDID to be on a Developer Account. You will still need a Mac though. In order to install this GM, you will need to use the iTunes 9.2 Beta, which is only available for OS X at the moment.

Some things to keep in mind:

You can not sync your iPhone to a Windows PC yet, since this build requires iTunes 9.2 Beta which is Mac only at the moment.

This is a Gold Master Candidate build, but does not make it an official build.  There may be bugs that end up getting fixed before the official version hits iTunes.

Here are the steps:

1. Download iTunes 9.2 Beta for Mac OS X
2. Install iTunes 9.2 Beta
3. Download the iOS 4 GM seed for iPhone 3GS, or 3G – iPod Touch 3G, or 2G
4. Plug in the iPhone (or iPod Touch) to your Mac, and start iTunes
5. Select your iPhone (or iPod Touch) from the left sidebar
6. Hold the Option key, and click “Restore“
7. Browse for the iOS 4 GM ipsw file and select it

Give it about 15 minutes, and you’ll have iOS 4 on your iPhone (or iPod Touch) ready to go.

I’m running it now on my 3GS, and it works very well.  It’s very responsive and stable.  I have had some app compatibility issues, but that’s because devs haven’t submitted their 4.0 compatible apps to Apple yet nevermind.
