Cool. Interesting that Alltel has some GSM networks.

My V195 on SpeakOut shows "SpeakOut" at 310-410 (AT&T) and "Other" at
310-260 (T-Mobile). Is the network number to name translation in the SIM
card?

My other V195 on T-Mobile shows "T-Mobile" at 310-260, and "Cingular" at
310-410.

What's strange is that the T-Mobile phone works at my house, whereas it
never did with other 850/1900 handsets. Either it's roaming onto AT&T,
or this handset is able to get a T-Mobile signal where other handsets
cannot. The T-Mobile coverage map shows almost no coverage at my house,
though they recently got approval for a new site that would give me good
1900 MHz coverage.
