The "January Software Upgrade" for the iPod touch, including Mail, Google Maps, Weather, Stocks and Notes. Mind you, this is not to be confused with the totally free 1.1.3 system upgrade, which brings the player up to date on iTunes 7.6 for rentals, etc., but has no apps of its own.
TAKE NOTE! YOU NEED TO BUY THE JANUARY SOFTWARE UPGRADE FROM ITUNES FOR $20 TO HAVE THESE APPS ON
YOUR IPOD TOUCH!!!
