You can't easily 'emulate a cell tower'.
To verify that the device isn't indeed transferring any data as part of any background Apple process they should put it on WiFi and monitor traffic through the router. It should be zero.
I'm logically assuming that any background process that would transfer data over 3G would also do it when on WiFi network.
They could also get a data modem from AT&T and test it by connecting to the tower but not transferring any data. If AT&T is overestimating data transfers or has phantom data then it would be across the board and would also show up on transfers through their data modems not just their iPhone plans.
