Priceline introduced a free Hotel Negotiator app for the Apple iPhone and iPod touch that enables you to bid for and book a Name-Your-Own Price hotel room up to 11 p.m. ET on the evening of your hoped-for stay.

Mobile applications are particularly geared for these last-minute — or, should we say, last-hour — bookings as travelers, who find themselves without a room, can use their iPhones to secure a room whether the would-be customers find themselves at an airport, stranded at an endless business meeting, or at the local saloon.

Last month, Priceline President and CEO Jeffery Boyd talked of envisioning a day when consumer behavior would change so that it would become more commonplace for people to book a room once they arrive at a destination instead of before the trip.
