How Do I:
[ Section I : Documents, PDF's, Books, Etc. ]
Save PDF's (from email, the web etc.) for later viewing?Many ways to do it including using iBooks, but I find the Goodreader app best suited. When viewing the PDF click on the "Open In" box in the upper right corner, then select Goodreader. To save from the web, use the Web Downloads feature in Goodreader, select Browse the Web, then click "Download Linked File" when selecting the PDF.
Print to any printer?
Get the Print N Share app, then use Airprint normally.
