Where's the Mute Button!?

So I recently upgraded the mobile phone I use for business. It's an HTC Hero and it is great, BTW. However, I have STILL not mastered the mute and/or hold button which is sometimes necessary as I have a 2yr old running around my office quite a bit of the time.

So, this is an apology to the customer that heard ear piercing screams. I had no choice but to hang up, call back and blame it on a wild animal outside my office window. We are in MN so we are more or less in the midst of either a forest or lake everywhere we go anyway, right? (Seriously though, many people from either the west or east coast have no idea where we are an those that think they do believe we are part of Canada.) Either way, I'm fine with it.

I sure hope I figure this phone out soon!
