UMTS
Will a UMTS phone work on a U.S. GSM carriers network? Just wondering, never really thought about it. I think no, but tell me if I'm wrong. I just wanna know becaise there are some freakin sweet Nokia comin out but they are UMTS and I want one *whining* 😛

First Cingular will probably use the 1900 WCDMA band, that is what ATT used when they introduced in the 6 markets.

I believe that there are currently only two UMTS phones available for purchase that would work on a U.S. GSM carriers network. Those two being the two that AT&T released on their UMTS networks, a Nokia and a Motorola.
The problem is since they are UMTS phones, due to size problems they cannot have all 4 bands of GSM. So unfotunately, where the variety of UMTS phones available from Japan and other places would be available, they will only contain the 900mhz and 1800mhz bands. Totally incompatible with U.S. GSM networks.
Hope this helps.

my UMTS phone has 900/1800/1900 GSM and 2100mhz UMTS and its rather compact given what it supports

A phone with UMTS 2100 (for Europe) will not work on U.S. UMTS networks, which are (or will be) 1900 or 850/1900.
But some UMTS 2100 phones for Europe/Asia include tri-band GSM, which will technically work on a GSM 1900 network here.
But for Cingular, you'd also need the 850 band for most areas, which no European UMTS phone so far has.
Plus most European UMTS phones are not sold unlocked, and are very difficult to unlock.
Plus, you'd be paying a lot extra for features that would never work here in the States... kind of a waste if you ask me.
The Nokia 6800 is a good example. It's a great phone, but you'd be much better off getting the 6682 instead, which is exactly the same, but strips out the 3G features you wouldn't be able ...
