same with document viewer, what format? I've tried everything, doesnt work tho
The built-in document viewer IS there =P I tested for compatibility when I first got the phone. For some reason Samsung didn't think it was necessary to make Office 2007 files compatible with the Behold, but documents created with Office 2003 work just fine (Word, Excel, Power Point) but it's view only. I imagine any older versions of Word, Excel, and Power Point should work as well though I have not tested any.
You can also view PDF files as long as they are not password protected (it will not give you the option to enter a password) and the PDF cannot be excessively large in file size. I don't know what the cutoff file size is, but I was able to successfully open a document that was about 2MB in size. Though when I tried to open one that was about 7MB or so, I got a prompt saying that the document was too large and it would not open.
Files made in notepad (.txt) are strangely not supported...not sure why.
The only other file format that I tried was HTML files. I know this sounds like a big DUH but for those of us without a data plan, this can come in handy. If you do not have a data plan and you transfer a HTML document saved from your PC onto your phone you should be able to view it. I can't remember if I was able to get any pictures to load, but I will double check and let you guys know.
Anyone know of any other formats that the Behold can view?
EDIT: So I just tested the HTML file and as long as you save a page as "HTML files only" the Behold can view it. But then again this technically isn't part of the document viewer since it will open the file in the browser, but it still works

Oh and if you don't have a data plan the images will not load since the image source comes from the original website. I tried saving the complete web page, but that didn't work so well...at least not for me.
