I have a feature that uses the camera so I can test it only on a device, I need to test it on older than iOS 4.3.5, However all of my iPhones are already at 4.3.5. Is there a way to downgrade the iOS so i could test it on older iOS?

  • If you have saved your SHSHs, you can downgrade your iOS version using tinyUmbrella (but I think that you may have to jailbreak) – Nasreddine Oct 11 '11 at 13:34
  • I didn't save the SHSH, anyway i think that 4.3.5 doesn't have jailbreak yet – Guy Ephraim Oct 12 '11 at 01:38

    It is quite lame that Apple doesn't give us a means to downgrade a device to aid in testing. The simulator can only test so much as my app uses the camera and other features not supported by the Simulator – ThaDon Apr 08 '12 at 15:21

Currently there is no way to do a downgrade to the iPhone OS to an older version unless the phone is jailbroken.

If your device was ever jailbroken, try looking into recovery of SHSH blobs to downgrade your iOS version. Otherwise, I don't know a way to achieve this.
