Restoring 1.0.2 Instead of 1.1.1
I have two iPhones, one that I've been keeping "clean and pristine," and that's the iPhone that I use most of the time. I do have another iPhone though, that I have done all manner of hacking and installing apps and the like. If, like me, you have an iPhone that you'd rather keep on version 1.0.2, it's easy to select older versions of the firmware when you restore the iPhone:
- On a mac, hold down the "option" key while clicking on the "restore" button. Then you can select the firmware file you want, just look for the file named iPhone1,1_1.0.2_1C28_Restore.ipsw, it should be in your home folder under Library/iTunes/iPhone Software Update.
- On a Windows PC, hold down the "shift" key while clicking on the "restore" button. Then select the firmware version you want -- you should be able to find it if you've restored 1.0.2 before by searching for all files and folders and looking for *restore.ipsw
