Need Support for Palm Pre Call Waiting

Question

I've had my palm pre for a month about now and notice a number of issues with its call waiting feature that need to be addressed.  Here is the list:
1) I can't drop 1 call without dropping the other call: this means that if I'm on the phone with person "A" and receive a call from person "B", though I can switch between the two easily enough, I can't end the call between person "A" to talk to person "B".  What's even worse, even if person "A" hangs up, the pre still keeps the call connected until I hang up my phone.  This is a serious issue when you're calling outside of any promotional time, nights, or weekends.
2) in a conference call, I can't end one conversation without ending both conversation.  So again, if I have both person "A" and person "B" on a call and I connect them through a conference call on my pre, I can't end the conversation with one without ending it with the other.  A real pain in the butt. 
I just want to know two things asap since I know this is something that'll take time to resolve (if it can be resolved)
1) is this a hardware issue or a operating system issue?
2) does conference calling really kill my minutes the way it look like it does?  I'm leaning toward yes from evidence I have, but I'd like to hear it from the pre reps.

Answer 1

1.  This functionality sometimes works and sometimes it does not.  But can you answer the other part of the post.  The PALM pre give the user no one to drop the other call.  Mine is worse.  If the other user hangs up CONFERENCE is still there; If they hang up I'm not in a CONFERENCE but the PRE does not recognize this state at all.  Therefore you can't add another person to the call again.
2.  This one does not affect me as much since I have the simply everything plan.  But I would def. pay attentiont my bill and complain to SPRINT every time this occurs.
3.  HAS ANYONE OPENED A TICKET WITH PALM FOR THE CONFERENCE CALL / CALL WAITING ISSUE?
