	    Phone: Double check mode before changing, part 2

	    A modem might report world phone mode when it really is only GSM or
	    CDMA capable, making the system switch to an invalid mode which
	    will later break the telephony code.
	    This simple check enforces the world phone overlay which is already
	    in place and will only consider it a correct value in that case.

	    This complements a commit with the same title by applying the same
	    logic to another code path that uses similar checks.
