10/7    An excellent web site showing you GSM coverage in the US.
        I'm very surprised that T-Mobile has a much better coverage
        in the US than Cingular, even as people claim that Cingular
        has a better coverage in metro areas.
        http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml
        \_ Add Cingular and AT+T together.  -tom
           \_ Hmm, even after doing so, I still see plenty of blank spots
              all over the Midwest. I have a 1900Mhz-only (ancient) cellphone
              that seems to perform very well in the inner East Bay, while my
              850/1900 Mhz phone seems to have inferior reception. Could it
              be because my 850/1900 constantly force itself to communicate
              with the 850Mhz tower (which is a rarity) while my 1900Mhz-only
              is happily interacting with the abundance of 1900Mhz towers?
              (just guessing) Both phones are through AT&T Wireless - jthoms
              [formatd]
              \_ it has nothing to do with 850 Mhz capability.
        \_ The Cingular=better reception argument doesn't really mean wider
           coverage.  The addition of 850MHz band from the AT&T merger gave it
           better building penetration.  850MHz signals penetrate buildings
           better.  I had virtually no trouble with T-mobile when I was
           outside.  It was the fact that I had no reception in my office that
           forced me to switch to Cingular.  I now have full bars in my office.
           \_ someone who are better at physics need to help me out there.
              I thought higher the frequency, better the penetration, but
              at the cost of having a much shorter range per tower.
              that seems to perform very well in the inner East Bay, while my 850/1900
              Mhz phone seems to have inferior reception. Could it be because my
              850/1900 constantly force itself to communicate with the 850Mhz
              tower (which is a rarity) while my 1900Mhz-only is happily interacting
              with the abundance of 1900Mhz towers? (just guessing) Both phones are

3/4     I'm thinking of moving to a shack in Montana.  Can I turn
        my tmobile cell phone number somehow to Skype ?
        \_ Yup
           \_ Has anyone done this?  Will they forward this to another
              number?
        \_ I recommend insulting your shack well.

           I don't get all of the iPhone hype. It's a phone. It's a nice
           phone, but it's a phone. It doesn't do anything existing
           devices didn't do, do them cheaper, or possibly even better (I
           haven't used one yet, so I can't say). Why is there so much

4/27    Anyone from the Beijing area here?  My mother-in-law is on a trip
        there.  She bought a SIM card there and put it in her cell phone.  She
        said the number is 1XXXXXXXX (total 9 digits).  What should I dial on
        my home phone in order to call that number?  I tried 011-86-1XXXXXXXX,
        but I always got a tone that sounds like a busy signal.  Thanks.
        \_ Try removing the leading 1. Many include the long distance dialing

4/19    I've been on verizon for a few years now, and haven't had many problems,
        but I don't like their selection of phones. I'm considering Cingular.
        Does anyone have any significant pros/cons for a Verizon to Cingular
        switch? Thanks.
        \_ You can't ask anything about phone companies and expect a consistent
           answer. It's like a game of the musical chair. Company A gives you

11/7    I don't know why this was deleted so reposting:
        Thinking of switching from Verizon to Cingular.  Mostly use in Mountain
        View and sometimes Berkeley.  Thoughts?
        \_ Cingular is pretty good in the South Bay. I haven't had any problems
           in the 4+ years I've been w/ AT&T and Cingular. One downside,
           Cingular's unlimited data plan is (was?) pretty expensive. --ranga

7/25    I transferred my land # to my cellphone, and I get all the junk
        calls on it too. Is there anything I can do?
        \_ Have you signed up for the Do Not Call list, at donotcall.gov?
           \_ If the junk calls you got were from auto-dialers, you can file
              a complaint with FCC.  Such calls are banned whether or not your
              cell phone number is on the list.  If the calls were from human,
