If the picture has that file name, it likely was taken by a BlackBerry, however, this is not absolute. A person could have renamed any file like this. You could look in the EXIF data.
Note, however, that simply "downloading and saving" a picture on a BlackBerry would not change the name of the original file and would not produce that type of file name (at least not automatically). Again, anyone can rename a file almost anything.
Thanks Bro. Whats the best way to get the EXIF Data? What software do you use/reccomend?
