Make sure USSD code only responds *#100# for retrieving own number 

strstr() was used with wrong argument order, causing it to always match,
and causing an invalid response to a variety of different SS and USSD
requests.

This has apparently caused havoc among a number of HTC phones which
issue SS requests without user interaction upon boot, and then trip over
our inappropriate response.
