Adobe released Acrobat app [iTunes link] for the iPhone. It is for users with an Acrobat.com account to give a way to share and view documents, fax documents and take photos of documents in one easy to use app.
Acrobat is created by scanR. To use this free to download app you need an existing Acrobat.com account.
The other side story is that you don’t get everything for free. You can only fax 2 pages for free or scan up to 5 pages, for all additional scanning or faxes you need to pay extra. Also it is not possible to use web conferences or online office applications, for these function you still need to visit Acrobat.com. Lets hope the next update will bring us some more free options.
