Is there any way to coax this dog turd,, to handle some more file attachment types?? Or at least allow us to save files that it doesn't know how to handle?

I read in several places, including here that MP3 attachments are supposed to work in emails, and yet, at least with firmware 1.0.2, they clearly don't for me. Did Apple intentionally remove functionality or am I missing something here?

This is a bit maddening. My Treo would at least let me save files that it didn't know how to handle in emails.
