Interestingly enough, the Google Gmail app for Blackberry devices does not allow at this time for the *sending* of attachments; viewing/saving however works nicely.

I’ve been writing some interesting Perl lately, some of which some people might find interesting or useful. Much of it is written for very specific situations, which are unique to an ISP environment.
