I just got an iPhone recently and after using the Maps directions for the first time today I was pretty disappointed. Previously, I had used Telenav on my Sprint phone which provided turn-by-turn voice directions. This is necessary while driving so you can just put the phone down and pay attention to the road. I tried to do some research on the web but came across some conflicting information on GPS navigation. Some sites had a "jailbreak" option and others announced turn-by-turn nav coming soon. I'm confused... can someone tell me if this is possible or not?
