Just today I ended a call, trying to place a call to my voicemail. The phone screen showed a "standby" mode - as if I was NOT making a phone call, though I could hear the voicemail prompts and the first message a friend left me.
When it came to pushing a button to save or delete the message, the keypad made a tone in my ear, but not a tone that the voicemail system recognized (remember, I wasn't on a call!). Somehow I think that Cingular will still be sure to charge me for those minutes, though...
Anyway, I had to pull the battery OUT of the phone to end the call, since no buttons would work.
Oh how I hate my Treo......
