You realise this is a forum, not a chatboard, AND it's christmas eve right?
Anyway, I tried opening at attachment on one of my emails. Just clicked the link at the bottom of the email to get the full msg + attachments, it said it would get it next time I checked my mail. Since the phone happened to already be checking I waited a bit, and now I'm looking at a .doc file I sent to my school. It's displayed at the top of the email and when I tap it, it opens in word mobile.
So I'm not sure what's not working for you, but maybe this helps?
