> How do you tell which band the phone is currently connecting to?
Someone stated in the last day or so that there's an AT command you can
send to the Neo's modem to tell which service.

The basis of my assumption is that only the higher-power 850MHz
frequency could make it through/around the concrete of our old apartment
building, especially since the Neo could not connect indoors on AT&T
whatsoever, but my Blackjack 2 could connect all the time, no matter
what. Also, the radio signal from the Blackjack 2 would cause any
speakers (computer, radio, tv) to buzz VERY loudly at the old apartment,
but at the new apartment where it shows me the 3G icon all the time
instead of the EDGE icon, it doesn't buzz any of our speakers even a
I don't know if there's any correlation between only seeing the EDGE
icon appear on my Blackjack 2 while indoors at the old apartment and
having the phone switch to 3G while outside as to which frequency I was
connecting on. I see from one source that EDGE can work on both 850MHz
and 1900MHz, the two frequencies used by AT&T, so perhaps I am still a
bit confused about it. I guess I thought EDGE only used 850MHz and 3G
was 1900MHz but I see from online documentation that that's not correct.
