editing PDF is not that easy..
Perhaps, I wouldn't recommend going down that route.
You need to convert the PDF file to documents and then edit it. but this can cause a few typos or errors here and there.
I have to edit .pdfs on the go quite a bit I have tried docs to go... super docs.... Mobile office (not ms) ......
Any one out there know of any one I am missing out on that could help me?
