Seen the message now. Interesting that they mention 100 free ebooks when registering your Sony ereader. Never got mine and when I queried it with Sony this was their response.......
Thank you for your recent e-mail.
I understand you have registered your Sony PRS-T1 and would like to enquire about the 100 free e-books.
Unfortunately the free e-books are not compatible with your Reader, however you can download the same titles for free from the Google e-book website. I have included a link below to this website.

Should you require further assistance, please do not hesitate to contact me.
Incompatible format? yeah right......
Not too bothered about the books but its kind of typical of Sony's level of support for the T1........
