    There is no easy way around iTunes for doing FW upgrades.

    As regrads backing up Apps etc....maybe...you need to do some more reading? Try this link iClarified - iPhone - How to Backup and Restore Your Cydia Applications Using PkgBackup

    Also - it is no real benefit upgrading to FW 4 unless your phone is acting up
    Do hope that helps
