    I have the correct file for the 3G and not the 3GS and I have iTunes 9.2 beta. I click on option then move the .ipsw and it starts extracting the software and bam, I get an error message number 3002.

    Anyone know what step I'm missing?

    Try and restore as new 3.1.3 and than update to 4.0 again.

    If I back up my iPhone, restore it to 4.0, I can't use the 3.1.3 back up to bring all the info such as text messages back to it can I?

    If not is there a way to update it or only a clean install will do the trick?

    I'd try this.

    1. Restore to 3.1.3
    2. restore from backup
    3. update to 4.0
