| I'm jumping in here 'cause you seem to actually know something about
these things work :).
I'm using a Nokia 6820 in mid town Manhattan - which should be cell
heaven - and getting a slightly different behavior. If I'm in and out
of a no-signal zone (like the subway), the phone will not re-acquire a
signal. Yesterday I stood in the middle of Rockerfeller center looking
at zero bars for 20 minutes - well I was doing other things also....
A techie at Verizon advised me to reboot the phone when this happens -
turn it off, remove the battery and SIM, wait a few seconds then put it
back togeather and turn it on. This does work - BUT THERE'S GOTTA BE A
BETTER WAY!
Any ideas??

Power it off and on with the power button?
That worked with my ancient Nokia 8290 which had the same problem.

Otherwise known as hijacking a thread.
If you aren't commenting on the original poster's question, don't dilute the
discussion -- go start your own topic. It's easy to do.

I had a Motorola cd928 which would get itself into a state
sometimes where it would never find a signal again, not even in
days, until physically switched off and on again.
This was clearly a bug, but Motorola would never respond to my
queries about the problem, or a firmware upgrade.
It's really a question of experimenting to find the minimal
steps that will jolt it back to life quickly. Perhaps a
"network search" or "choose new network" (but selecting the
existing one) from the networks menu might be easiest if that
works, especially if you can set that up on a key or user menu
(I'm not familiar with that phone).
On some phones, you can set the automatic network search speed
to fast or slow. Fast search should reduce this problem at the
expense of battery life.
Doesn't a simple switch off/on fix it? If not, I'd call it a
bug.

Probably not. Looking for a BTS is fairly hard on a battery, so when
you take the phone into an area without service, it tries a few times
quickly to locate another BTS. After that, it may be 10-20 minutes
before it decides to look again. It is a way of saving battery power.
I used to see that problem in rural Australia. I'd drive right by a
tower, and still see 'no service'. Power the phone off, power it back
on, BINGO!

I can certainly confirm the extreme manifestation of that
behaviour when the reason for the "no service" is an initial
contact with the BTS at greater than 35 km. In the absence of
another BTS, some phones don't try the TA-fail BTS again in the
time it takes to drive the 70 km across its usable range.
I've assumed that this is a result of firmware that's designed
for more populous locations.

My nokia 6256 has been rebooting for no apperent reason when I unplug it
from the charger and close the lid. It's happened like 2 times in the
last 2 days.

There should be, but.......
On my Palm Treo 650 (GSM) I have the same issue, and I have to do a
power off/on routine, especially when roaming overseas and trying to
acquire a carrier for the first time.
In fact Palm recommend this if there is a problem obtaining a carrier
after turning the phone on, whether roaming or not. Power off again,
then on.
So much for modern technology!

For something as programmable as a Treo, why couldn't somebody write a
"Re-acquire Signal" application and assign it to a seldom-used button? There
has to be a piece of code already in the OS to perform that operation.

What's a SIM doing in a Verizon phone?
