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.</span></div><div><span>There is also the problem with large bursts - every time (downlink or uplink, doesn't matter) the capture stops.</span></div><div><br><span></span></div><div><span>Cheers,</span></div><div><span>Bogdan<br></span></div><div><br></div><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><font size="2"
