.JPG "cannot be viewed on your device"
 

Here's a new one for me.

So I got an email with a regular old .JPG attached. In the email it shows the attachement file type as a paper with a question mark in it... when I tried to open it it pops up a notice that says: "This attachment type cannot be viewed on your device" and forces me to click "ok" Same thing happens if I try to D/L the attachment it then tells me: "You are about to D/L a file that cannot be viewed on your BlackBerry device. Continue?"

Any idea why this is happening and how I can remedy it?
