Hello!

I just got my first e-reader, a sony t1.
i have downloaded some of the free classics. and after i figured out the adobe issues everything went great. now i'm having a hard time to get other books on my reader. i tried to get some books in pdf format, but it said the content wasn't supported. what's that all about?
any help would be greatly appreciated, as well as any other useful information!

Thanks,
