Okay, that's the third person who has said they've tried calling me on my cell phone and they've gotten "number is disconnected" or a busy signal (it usually goes to a message about my email instead) or all kinds of other things.

It's too late for me to go to AT&T and see if something is wrong with the phone.  I won't be able to look into it until Monday.  So if you try calling my cell and you don't get through, my phone is on the fritz.

And to those of you thinking I'm just looking for an excuse not to take your calls:  when I don't want to talk or be interrupted, I turn my phone off.  So, no, I don't need an excuse to not answer.
