While the Google Maps update for iOS is barely out of the cellophane, Mountain View's keeping up the momentum with a matching SDK revision. Version 1.4 of the developer kit for iOS maps allows app makers to hook into some of the new features, and bring them right into their own creations. Now, you'll be able to add Street View imagery -- with optional markers -- from over 50 countries (including recently added landmarks), introduce floor plans, and benefit from the more neutral maps design. There's a slew of bug fixes too, which can be found at the source. Want the info from developer relations at Google Maps directly? Then, head past the break for the video walkthrough.
