When they are packetized and sent over the network, phone calls become data.
There is a difference between at&t's 2g and 3g networks. Both in coverage and in the voice codecs used to compress voice into data.
It is unusual to find a place that has strong 3g coverage and poor 2g. As at&t usually deploys them on the same cell sites. But I suppose it is possible.
One way to test this would be to disable 3g on the q9h and use it on the 2g network. If you have problems similar to those you are having with the BB then you can start looking at the network as the culprit.
Once a 3g BB is available on AT&T it will use the same network the q9h is accessing now, if that works better for you so will a 3g BB.
