I plugged my phone into my mac and mounted the sd. I copied all the files/folders on the sd (the ones that were shown in finder). Then I formatted my sd card and copied the files I thought i needed from my hard drive back onto the formatted sd card. Now the apps that i had stored on my sd (via the froyo implementation) don't work. I assumed they were saved on a separate ext partition (like the apps2sd/apps2ext before froyo). But alas they were not. Turns out froyo stores it on the fat partition (apps2fat).
So in short: where are the apps stored on the sd? Is it "invisible" to finder?
I know I should have made a disk image and not just copied the files/folders when I "backed it up".
