i was thinking about this the other day. the gps has it's own
processor, correct, and can act independently of the cpu? i'm
wondering if it's possible for the gps to keep it's fix while the main
cpu is in suspend. power usage will be higher than a full suspend, but
the phone will have a fix as soon as it resumes. is there any reason
why this can't happen?
