Since I upgraded to Android firmware, my PDN doesn't read anything off of my internal sd card. I never took out my sd during the upgrade and I'm wondering if that may have something to do with it. The wallpaper and layout is new, but I can't open anything (ebooks, music, android apps...) that I have on my sd card. QUESTION: I'm wondering, if anybody knows how to transfer files from the sd card to the Android PDN? Or is the problem maybe that that I did something wrong during the upgrade?? Please help, I've been stuck for hours!
