up and loses service.

I am on my second Moto MPX 220 since Dec. 20, 2004 (in fact, Cingular
is sending me my third 220 tomorrow.)

My current problems are:
1)my phone will show "No Service" and I cannot receive calls or message
notifications but can make all the outgoing calls I want.  Upon making
a call the signal bars will light up to my normal range but as soon as
the outgoing call is ended it will show again "No Service" + the
ghostbuster symbol.  This happens about every 7-10 days and can be
fixed by hard reset (pulling battery out while power is on.)
2) Every 3 days or so my menus will be slow to come up and upon
receiving an incoming call (if not suffering from problem #1 above) the
caller ID will freeze and the ring will freeze on one note and I am
unable to answer my phone until it un-freezes (often I am not able to
answer before the call rolls over to my voice mail).  This problem can
also be fixed by doing a hard reset as described above (so now I'm
having to reset my phone every couple of days!?!?!?)

As mentioned, this is my second phone (have only had it for ~2 weeks)
and on my first phone I was experiencing problem #2 above as well as
the display looking like someone changed the resolution on the screen.

I feel most certain that I will be sending my 3rd MPX 220 back to
Cingular in about 2 weeks or so as noone at Cingular is willing to
admit there is a problem and will only send me new phones with the same
problem.

Has anyone else out there experienced anything like this?

Thanks everyone!
