That's a good point, Tupshin. You (and the community) can guide us as we<br>try to figure out how to proceed.<br><br>How many of you must have 850 MHz support, and would be satisfied with<br>an 850/1800/1900MHz variant, and how many of you must have full quad-band?

<br>Michael<br></font><br></blockquote><div><br>I've already put myself down on the list for the 850 tri-mode. That'll work "good nuff" for me. But I also did some digging around on GSM World to hopefully answer my questions and others. If you take a quick look at
<a href="http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml">http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml</a> which is the US list for GSM based operators, you will see it is universally 850 or 1900 (or both). In the case of AT&T you can take a quick look at the two coverage maps: 850:
<a href="http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=b2">http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=b2</a> and 1900: <a href="http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=be">http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=be
</a><br><br>From what I can see in the maps for AT&T is that 850mhz isn't as well rolled out, but where it is, has better coverage. 1900mhz is better deployed, but seems to be spotty when it comes to the fringes. But the short version is that without 850 access on the moko, I personally would be unable to use half the towers around here. I'm going to go as far as saying that 850 is critical for
U.S. GSM.<br><br>I'd suggest everyone find their country on GSM World: <a href="http://www.gsmworld.com/roaming/gsminfo/index.shtml">http://www.gsmworld.com/roaming/gsminfo/index.shtml</a> and check their providers. Unfortunately some of the maps don't differentiate between 850 and 1900 (for example Rogers Wireless in Canada). The other two Canadian carriers listed, and the Mexican seem to be 1900 only. So it looks like the US just wants to be different, as usual.
