I'm having trouble transferring photos I took with the X, onto my macbook pro. When I connect the usb cable and choose usb mass storage, it just tells me the sd card is busy. If I open the phone storage icon on my desktop, the only files that show up are the ones I transferred from the computer to the phone. And if I try to use iphoto to import them, it can only access the photos I had already transferred from my laptop to the phone. It seems like the photos I took on the phone are inaccessible to the computer.
