Help Can't open email attachment


I have the Samsung Captivate and I'm totally new. I'm having problems opening my email attachments (pdf and xls). I found this thread, but I'm still confused. I can't seem to find "open unknown apps" nor "Unknown Sources" in my Settings.


I'm having the same problem, I don't see any open unknown apps when looking through application settings. I am a recent convert from an iphone, and other than this problem I have been happy with the switch. I'm trying to open a word document. It just says "this attachment can't be displayed". Help, please!

You can download apk attachments from the gmail app but you have to log into gmail thru the browser to download all other attachments.

It sucks I know.

I redirected emails from my business account to gmail acount. When I get email which consists no att whit some text in body and when it redirects to gmail (pc and android phone) i get a message WITH att named untitled attac... and cant open it. BTW, i CAN open another att which was there in the first place (before redirecting). What is going on?
I can't seem to open an attachment(picture) attached to a text message. I also just got started with a "smart" phone and am beginning to wonder if it's smarter than me!
