iPhone OS 2.2.1 Back up

Question

Hi All,

I know by this time that there is no way to down grade from 3.0 to 2.2.1. So, can any one tell me how to take the back up of the iPhone device with 2.2.1.

Thank you All.

Answer 1

You will not be able to restore from that backup to get 2.2.1 after you have upgraded to 3.0.

However, if you want to make a backup, simply connect your phone to your PC or Mac and itunes should back it up automatically.

If it doesn't, right click on the iPhone icon in the left panel of iTunes and select "Backup".

The backup will back up your settings and documents, and you might be able to restore those using that backup.

To restore, connect your iphone and hit the "Restore" button in the iTunes page for your phone.

Here is how you can downgrade your Firmware: http://www.blogsdna.com/2733/how-to-downgrade-iphone-firmware-30-to-221.htm

Backup: If you've a jailbroken device, you could use SSH to access your needed files.. I don't think that there is an "easy" way to load a 3.0 Backup to a 2.2.1 phone (if I've understood your question correctly).

Cheers

If you want to get to files in the 2.2.1 backup, you could use a backup extractor. There's a free one at http://www.iphonebackupextractor.com that'll do it.

Putting the files back onto a newer iPhone could be tricky, depending on the files you're after.
