I did a search already and it seems you can restore backups from any firmwares?? Correct me if i'm wrong but the backups just backs up the settings etc right?? So if i back those up, and upgrade or downgrade the firmware, i will be able to restore the backups right?? Well i tried that through iTunes, but it asks me to restore to the firmware that the back up was made. Is there an app that i can use to make back ups properly without asking me to restore to the firmware?
