I know there a number of threads out there on this, but want to ensure that I undersand completely before buying anything (or a number of things). The Mail app on my iPad2 is set up to receive incoming emails, many of which have Microsoft Office documents (e.g., excel, word, ppt) and PDFs. I need to be able to do the following: View all Documents Save all documents directly from Mail to Ipad2 Edit (excel, word, ppt) Re-save documents already saved on Ipad2 Email saved Documents I've read through the forum I don't know if i've found an app that does ALL of this for each of the types of files (excel, word, ppt, pdf). Is there ONE app that I can purchase that does all of these things for all of the types of documents that I may receive via email? Thanks.
