That technique is unreliable, at least through Android 1.1. On my G1,
for example, getLine1Number() returns the phone number that my SIM was
originally set for, before I ported an existing mobile number over to my
account. Others have reported null values. My assumption is that this is
a SIM-specific issue.
I am not aware of a perfect solution to get the device's true phone number.
