Hey guys, newbie here. Just got my iPhone 3GS in the mail. I had a service called TeleNav (www.telenav.com/products/tn/ to know what I’m talking about) on my Blackberry and absolutely loved it. I just heard that they just released their service on the iPhone. I am unsure of how it is going to be because of the touch screen. Does anybody have TeleNav on their iPhone? If yes, how is it?
