Cellphones, bluetooth and serial connections

Question

I have used a GPRS-connection with my Powerbook connected to my cellphone via bluetooth for a couple of years now. However, I have one problem with this setup - I have several cellphones (A, B, C) and subscriptions (1, 2, 3) and I can only connect with the most recently paired phone. In other words, if I first pair A with my computer and try to connect using 1 it works fine. I then pair B and try to connect through 1 (I have moved the SIM-card for 1 from A to B) it still works fine but when I now try to connect using A, the connection, and this is no surprise, fails. The reason it is no surprise is because the computer still tries to connect using B.
I don't know why this happens, but there seems to be some limitation in Mac OS X/the Bluetooth setup process which only allows it to use the most recently paired phone.
In other words, in the situation described above, the only way to be able to connect using A again is to "unpair" both A and B and the "re-pair" A.
Very annoying. However, after digging around a bit in the Bluetooth prefs I found: Devices tab -> select a phone in the device list -> Edit Serial Ports… where you can add serial ports (two different types of serial ports: "Dial-up networking" as well as "Serial port") for your devices and then make them visible in the Network pref pane. I guess this means that it is possible to add a serial port that belongs to a specific BT-device and then create a network location that uses this port/device and suddenly my problem would have disappeared.
The problem is that this window is unsupported. Yes, I have called Apple Assistance and they specifically says that this window is not supported by them, not even if I paid a technician or engineer at Apple (I support more than 20 users at my company that needs this functionality, hence my eagerness to pay for support). They actually laughed at me when I said I was prepared to pay to have this issue escalated.
Back to my question: I have tried to add both types of ports in different combinations but when I try to connect it still fails. In Mac OS X I get the following error message:
The modem has unexpectedly hungup. Please verify your settings and try again.
and a verbose internet connection log looks like this:

Any ideas how to get this to work?

Answer 1

I wonder if just using Network>Configure>Show>Network Port Configurations, then selecting the existing Bluetooth/Serial connection and duplicating it as many times as needed, the editing them wouldn't help... then you could just have a location for eack Phone.
