I take underground subways in a metropolitan are in USA and notice that people are still able to use hand-held devices. Are they accessing the wireless Internet? How is that possible considering that one cannot get a wireless signal for their cell phone in the underground subways?
It depends on the city. In NYC, most people are reading cached e-mails on their BlackBerry/iPhone or playing games that don't require internet access. There are a couple places where you do get wireless from the train like when at the Penn Station stop. Which updates the e-mail cache.
Some cities are talking about setting up wireless access underground. Don't know if anyplace has yet though.
I just spoke with ATT trying yet again to improve the sound quality on my cellphone. No help at all. In the two years I've been on contract, I have tried four different phones (Motorola, LG, and two Samsungs). All lousy. I know plenty of people who have great reception, some on ATT! Do you guys know what I can do, short of tossing this thing little nerve-eating device in the river?

Some phones have better radios and/or antennas and simply work better in areas with cra*&^ weak signals. Also, some guys live in towns where AT&T is not terrible, overloaded, etc.
There are also separate issues with voice and data. Which are you concerned with?
The good news is that AT&T is spending a fortune on upgrading their network. The bad news is that almost all (100% all?) of the money is going into LTE which will not help you (a) today and (b) will require new phones.
