This is going to sound incredibly obvious to some of you, but I don't get how to use the apt backup. I reinstalled 2.1 then used qwkpwn to jailbreak. Before doing so I used the apt backup and then backed up my phone. That of course wiped out all my jailbroke applications. So then when I reinstalled app backup and try to restore, it won't because it thinks I never made a back-up (but I did). Hope this is clear-thanks!
