This question is aimed specifically for Kindle books I purchased. The only problem is that I no longer have the phone and I'm using Andy's Emulator and I want to read a book I purchased
Erm... So you're using Andy's Emulator, but did you transfer over the files on the phone? They'd be split between the phone's internal memory and the SD card; if you didn't save the data on the phone before you got rid of it, you wouldn't have a way of accessing those files.
Basically, I'm just looking for a more detailed explanation of what setup you have.
