Highly unlikely. As with the T610, it is only GSM 900/1800/1900. I suspect
they will likely have another version (T636 to follow the 610/616 scheme?)
for use on cingular with 850/1800/1900, which will be functionally identical
(as are the 610/616).

Can you tell me about GSM 900 vs. 850 -- who uses what?

GSM 900 is the most common flavour of GSM you will find practically
everywhere except the US/Canada/Mexico area, Japan and the ROK.

GSM 850 is yet another unique "US only" standard.

GSM 900 is used in most of the world MINUS the Americas. Where GSM is used in
the Americas, it is in the 800MHz band (mislabeled by the carriers at 850 to
cause confusion and allow them to try to sell it).

Here in the states, companies like Verizon (AMPS/CDMA), AT&T WS (GSM, TDMA,
AMPS, and GSM) and Cingular (GSM, TDMA, AMPS, and GSM) and many smaller
carriers that are legacy cellular carriers use 800MHz.

As a new user you really shouldn't concern yourself with the underlying
technologies. You should buy what will work for you where you want it to work.

"GSM 850" was actually chosen to minimize name confusion with TDMA 800 (which
it overlays), just as "GSM 450" was changed to "GSM 400" to minimize name
confusion with NMT 450 (which it overlays).

what about the higher GSM frequencies?

Cingular uses the 1900 and 850 (800) bands

There is 1800 in the rest of the world and 1900 in the Americas.

There can't be any confusion. The name is GSM.

The frequency band is transparent to most users and thus shouldn't be a
concern. However the official FCC nomenclature is the 800MHz band and the
1900MHz band.

It was simply a marketing gimick and not even much of one at that! You don't
even see the technology mentioned in the advertisements any more.

When digital first came out it was of course called Digital. Then when the PCS
lisences were issued all the advertising for the legacy 800MHz carriers was
changed to PCS even though they were still cellular and not PCS. Just an
advertising gimmick.
