it is kind of possible to lock frequencies using the *#*#4636#*#* by pressing menu while in the phone info screen and then selecting select radio band. It would be great if someone could design an app something like the nokia nemo/fieldtest app with the ability to easily lock frequency, carrier(uarfcn) and scramble code (psc). apparently the samsung galaxy has these sort of features in built, is it possible to rip it out of a rom and put it on to the desire if a standalone app cant or isnt created? This would save us a heap of time testing bases!
I'm looking foward to the same issue: Lock a particular channel to analyse voice and data traffic. Does anyone know something about it?
