Was curious if there exists a list on the web or if someone could provide a
list of Class A GSM Handsets? My interest is in transmitting GPRS while on
a voice call without a hitch.

I don't know of any. But most 3G (WCDMA) devices can do that.

I wonder whether you mean real class A handsets or ones supporting DTM (Dual
Transfer Mode)? I don't know any of the former sort, for the latter there
are several Nokia handsets with DTM available (I'm not sure if any other
manufacturer has DTM-capable handsets out on the marketplace).

However, note that DTM requires network support ; as far as I know,
unfortunately no operator in the US supports it.

Of course, in 3G (WCDMA) multi-RAB (simultaneous CS and PS
connection/transfer) is a default feature.
