Good Blackberry ebook reader

I have recently got myself a Blackberry 8800 phone.
While it is not the latest and greatest model it is still a very good smart phone.
One of the first things I wanted to do was find a ebook reader for it. After some trial and error and I found the KOBO reader an excellent choice.
You can get it from Blackberry App World or from Kobobooks
Kobobooks has a fairly good selection of books to choose from and most are a good price.
