More Efficient iOS Updating for Mutiple Devices: How to use IPSW files | OSXDaily


This article tells you how to download the software for your iOS devices directly in Safari and then tells you that you can tell iTunes which update to install manually.

However, there’s also a great use for these directly-downloaded files if you have multiple iOS devices to update. Use the referenced links to download multiple iOS updates simultaneously—the total for downloading all of your updates is as long it takes for iTunes to download just one update. Then put the files into the appropriate ~/Library/iTunes/(iPod/iPhone/iPad Software Updates) folder.

Then, when you plug in your iOS device for updating, the download process is skipped, the update is verified, and you’ve saved yourself waiting for sequential downloads to occur.

Is this a big deal? Could be. I plug in multiple iOS devices and update as many as I can simultaneously and once you click “Update” for one of them, all operations are halted for the others. (You did know iTunes will do more than one device simultaneously, didn’t you?) Last night, I had to update two iPads, iPhones 3G, 3GS, and 4, and iPod Touch G2. That’s five firmware files and would have been about 1.5 hours of downloading via iTunes vs. 15 minutes with Safari.
