Siri will work on both connections when required. Yes, Apple still uses Google maps for providing directions. However, Apple partnered with YELP to supply local search rankings for businesses.

I wonder if the new Iphone OS will carry Siri towards older models (3GS and 4)? Or this will only be exclusive for 4S?

I will bet that Apple will sell millions of these no matter how heavily it is criticized. What will surely tarnish its appeal is a repeat of what happened when they launched Iphone 4 (remember antennagate?). I'm hoping Cook and his clan is driving Apple in the right direction.
