When I go to
http://www.wireless.att.com/coverageviewer/
and put my address in, the map shows a solid dark blue for data, but for
phone service, my neighborhood is a light orange patch surrounded by a
darker shade of orange. I can't find a #$%^& key for the colorcode! Does
anyone know?
I ask, because I contemplate a switch (from Verizon Wireless) to ATT (for
the iPhone), voice and data.
Thanks,
Ron

Re: How to read the ATT coverage viewer.
Now the legend appears below the map. Maybe it hadn't completed download
before. Sorry to post in haste. -Ron

Only the best coverage should be trusted on those maps.

Why?
The data coverage map is bogus (Verizon- or Sprint-style, all one color
anywhere they imagine you might be able to get any level of service), but
the voice coverage map doesn't seem to be so bad. For a calibration
point, my house is just inside a light orange area less than a block from
where the map turns yellow and both the voice and data service work okay,
if not exactly perfectly, inside my house.

Thank you, that observation is useful to me. My house is in a light orange
pocket surrounded by a dark orange area. So maybe there wouldn't be a voice
issue (despite what the legend says)?
I'd appreciate hearing other experiences correlating the map predicitions
with reality, particularly for the iPhone.
Thanks, and Happy Txgiving to fellow Yanks here,
Ron
Incidentally, I now realize the reason I never saw the map legend (my lead
post) is the window (firefox) came up without a vertical scroll bar. Later,
it did. Go figure.

The handheld doesn't make any difference to the quality of the coverage
map.
In my experience, the coverage map provided by AT&T is reasonably
accurate. In the places I've bothered to actually compare the map
against reality, my average signal strength has roughly corresponded to
what's indicated on the map.
However, Ron is partially right, but I'd reverse the thought: Don't
fully trust an area marked a poor quality. In such an area, you could
have anywhere between two bars and no service.
Note that with GSM phones, two bars of service does not noticeably
degrade the quality of the voice connection, and if you do get/receive
a call in a poor quality area, the tower will usually increase its
power output on your channel to boost your reception for the duration
of the call. At least, that's been my practical experience: I could
have only one or two bars showing, get or make a call and the signal
strength shoots up when the call connects. This was with three
different handhelds: Treo 650 (my first GSM unit), Treo 680 (replaced
the 650) and iPhone (current unit).
