greetings Curt, et al,
it says 4096 color LCD, then probably be a sibling of N2001.
the new N2002 features 64k color.
about the compatibility, what's the 3GPP version used on Isle of
Man? DoCoMo was allocated FDD band-B, 1940-1960/2130-2150 MHz.
they also modified the protocols, hence the name J-WCDMA.
on SMS, maybe it's not directly accessable by the user, but is
needed for message notification. a key feature missed in DoCoMo
2G PDC, where the center only tries, via modified HTTP (ALP),
to deliver a message only once and never retries if failed.
does anyone know if the UMTS-GSM handoff is possible, regardless
of the cost (of a dropped call)? anyone has more information on
ZEBRA, which was dicussed here before? I'm really interested.
cheers,
Ken

Ah, right. Got me on that one. Never mind that the test is not as
advanced as a current production system. Oh well. Another case of
"journalism," I guess.

Oh, was that actually a requirement? It sounds rather..difficult.
I think even putting GSM and 3G in a single phone that didn't weigh
a ton would be a pretty good achievement. You might be able to live
without the handover if you had good coverage within the areas that
do have 3G, though I think that FOMA has shown us how hard this
can be.
At any rate, I've appended the response I received.

I've only been to the IoM so can't really compare. The IoM handsets are not
compatible with Tokyo although they couldn't say why "something to do with
i-mode" was the nearest I got to an answer. They seem to be really on top of
both radio planning and billing, but as far as services are concerend I
suspect everyone will have to learn from hutch 3G.
