Support USSD messages, e.g. for "remaining airtime" checks

gsmd and other related applications should support USSD (Unstructured
Supplementary Service Data) messages from the carrier. This protocol is used
with some prepaid plans to check the remaining balance. For example, with Fido
Prepaid (Canada) I dial "*225" and get a USSD response indicating the answer:


%CPRI: 1,2
+CUSD: 0,"Your balance is $55.15, expiring at 00:01am 15022008 (DDMMYYYY).
Refill before this date to keep your unused balance. Thank you.",15


These messages may also appear when a regular call is made, e.g.:



%CPRI: 1,2
+CUSD: 0,"Reminder: Airtime expires soon. Please refill to avoid losing airtime5

%CSQ: 21, 99, 2

There are probably other USSD-related functions that should be supported at some
point, but just passing these messages through to the user's GUI would be a good
start (and would be required for a "consumer-ready" phone).

Just for the record: Qtopia does display +CUSD messages, or did in the past.

I don't think it's a qtopia issue.
And I think it's already solved.

First things first, you should set a hard and fast target date when ever you will completely quit, such as several weeks from now. He is content, as well as the complete opposite of what we think old age has in store for us.
