why not just download the PDF to your phone for free??? Depending on what the app offered, it would have to be more than what I can get from the PDF or the website from my phone or it's not worth anything - not even .99 cents.

The ones in the android market are NOT from the states DEP but from a company called High Ridge Software

It looks like they are jsut reformatting the PDF file to a more friendly format which I guess if you use it a lot is a nice thing.
