Tonight, I decided to refresh my jailbroken iP4...so I figured I'd go to iTunes 10 and restore to factory settings. this is what I found... 1. it appears iTunes FORCES you to upgrade to the latest rev of iOS4. When prompted, it asks one question: Do you want to restore your phone to factory setting and the latest edition of software? 2. The latest avalable edition is 4.02, so I did not to the reinstall.
