FS#1363 - QMI does not use correct APN

I tested the fix recommended by Evren on my home KPN NL connection and it is a partial success:

1. If I apply the recommended patch and I want to key in specific APN, that is now activated and the connection is set up, and it does not matter what AT+CGDCONT? shows.

2. However when I want to activate the default APN where the APN string is empty, that still does not work. I suspect in this case it is again the AT+CGDCONT value which gets activated (incorrectly), but I can only check this on monday.
