Hello,
Luca thanks for your reply. Regarding the phone I used, there were a few smartphones which I put them in EDGE mode, but also some older like Nokia 6310i which only knows GPRS. The cable is FTDI. However I haven't got any luck - only a few times I get somthing that can be decrypted but there are only 2-3 malformed packets. There is also the problem with large bursts - every time (downlink or uplink, doesn't matter) the capture stops.
Cheers, Bogdan

I used a Blackberry Test Field to disable EDGE and identify which ARFCN that doesn't hop on GPRS: ( eg. this one is hopping, others may not [1] )
Could you clarify how did you do this? Following your recommendation I recently got a BlackBerry too, but after a quick look into its engineering menu I didn't find how to disable EDGE.
And a related question. It requires a code to enter to the engineering menu. Do you have any script for calculating it offline?
(I'm sorry for off-topic, but I think this may be interesting for other people too, because BlackBerry engineering menu is really that good)
