for the pdf viewer replacement...
only copy the file into a dir on your cf card and install with a "click" and you are a happy FULL-SCREEN reader :-)
i have problems by using the calc48x .....
BUT !! Using the developer-pack an/or the (very good) comunity software are on your own risk !!
... i only work with a win - device and with VStudio or SQL ... before the iliad i never seen a linux system in my house... but yes, the ipdf viewer runs .-)
i also need help to understand the linux system and the dev-pack ....
