Download iOS 4.3.2 for updating multiple iPhone 4 devices

When there are multiple iPhones in a household and you want to upgrade them all from a single iOS download via multiple Macs, it can be a bit of a challenge. I have previously blogged about how to do this. This post contains the link to the latest version of iOS for the iPhone 4.

Using a proxy

I again used Charles to capture the url of the iOS 4.3.2 firmware update file (.ipsw). I had to enable the SOCKS proxy options this time to capture the traffic successfully.

Enable the SOCKS proxy in Charles by clicking on Proxy > Proxy Settings in the menu and checking the Enable SOCKS proxy checkbox in the Proxies tab.

Also check the Use SOCKS proxy in the Mac OS X tab.

Download URL

The iOS 4.3.2 firmware update file (.ipsw) that iTunes was downloading is clearly visible in Charles:

Update

Update each iPhone as per my previous post.
