Hi, I am new to the IPAD2 world and I am trying to use it in my real estate business... I would love to add a png photo of my signature but also to be able to type text as needed in the PDF's... (not the pdfs with the fill in boxes).. I also get the occasional scan of an UPSIDE down pdf- and I must be able to rotate it... I am not savy with all the apps out there- and purchased QuickOffice and its not much help Any help would be greatly appreciated!!!
