If you haven't saved your SHSH before updating then there is no way to downgrade. Saving SHSH isn't commonly done with iPhone users that aren't jailbroken/unlocked.
You can not downgrade any app. You can update, but not downgrade. There is nothing that you can do. Sorry.
One way to downgrade an iPhone 4 is to go into settings on the phone and reset it to factory settings.
You cannot downgrade an iOS device without installing illegal hacks.

No once you downgrade, you will be able to throw all your information including contacts and photos on to the new iOS that you downgraded to.
You have to find an old backup of your iPhone and restore your phone from it. It will depend where you have stored your backups either on your computer or via the Cloud. If you only want to downgrade because of the camera, it just takes a little getting used to is all.
you can't... but if you are doing this because of your iphone or ipod not syncing, you can update your phone to keep up with the new itunes
Only the original iPhone should even be capable of physically achieving running that iOS version. And even then, you are not allowed by Apple to downgrade a device which would mean using hacks.
