ok so I've read the first 20 pages of this thread and googled for more info as well and still can't find what I am looking for. I see references of a Nokia N97 and Nokia N97 NAM. are their two different versions? Waht are the differences? Main reason I am asking is I need 3g 850 and so far I hear this phone does not cover it. If anyone can confirm this detail for me, I'd appreciate it. Thanks.
***EDIT***
I may have found my answer:
"If you mainly want to use the phone in the USA, you want the NAM version, not the one you get in Europe.
The main difference is what UMTS (3G) bands it supports. The International version supports 900/1900/2100 MHz, whereas the NAM (North American) version supports 850/1900/2100 MHz. AT&T Wireless uses 850 and 1900 MHz for their UMTS (3G) coverage, with a trend towards pushing more over on the 850 MHz band. Internationally, 2100 MHz is most common (also in Europe), whereas the 900 MHz has only very recently been added/introduced in some European countries.
Someone mentioned something about "tri-band" and "quad-band" -- those are entirely useless terms these days. They pertain to GSM (2G) frequencies; most, if not all smartphones these days are "quad-band" in this respect. (Again, the issue is that North American networks don't use the standard frequencies deployed internationally).
FWIW, none of these phones will give you 3G coverage with T-Mobile USA - they use an entirely different band, 1700 MHz. Also, they won't work with other U.S. carriers such as Verizon, Sprint, Nextel, US Cellular, Alltel, MetroPCS, etc - since these use different technologies altogether (CMDA, iDEN, etc). So, mainly, the N97 NAM is a phone that's optimized for AT&T.":
Correct?????????
