I think that some email messages that I send to iPhone users may be hard to read, even though they are easily readable on a PC. I assume that screen size and formating limitations on an iPhone may scramble the appearance of some messages. My question is, are there any file formats which cannot be read at all on an iPhone. For instance will an iPhone read PDFs, XLS, DOC, DOCX OK or at all. Are there any known limitations where the file must be opened on another sy= stem?
