    Hi Im a first time poster lol. My daughters iPhone 3Gs got stolen and I had a 3G as a spare and was wondering if it was possible to use her last back up from the 3Gs to restore in the 3G? Thank you.

    This will only work if:

    a) The 3G's firmware is higher than the one that the 3Gs was on.


    b) The 3G's firmware is the same as the one that the 3Gs was on.

    For example: If the 3Gs was on 4.3.3 and the backup was from 4.3.3, the backup cannot be restored to the 3G because the latest firmware for that phone was 4.2.1.
