I just got my kindle today. Was waiting(not so patiently) to FINALLY get it. Then i find out i can't use the whispernet, tech said no prob download the books to the pc. So i do. but when i try to read them on my Kindle i get a message saying the selected item could not be opened, try redownloading, if that doesn't work call tech back.....well they had no clue as to why it won't let me open these items and did several different walk throughs....Anyone else have the same problem???
