If I don't care about Siri, shall I just get an iPhone 4?

As much as I'd love an iPhone 5, they're really expensive, I'm only 14 anyway and I have Siri on my iPad and I don't even use it! I don't want to pay for something I'm not even going to use, do you recommend just getting an iPhone 4? Ps I live in the uk so iPhones are a little more expensive here

I just got a ticket for using google maps for directions on my iphone while driving?

The officer spotted me looking down on my lap but didn't see my phone at all. After pulling me over, he stated that I was using my phone. I told him no and that I was getting directions for a delivery I was about to make. I further explained that I work as a delivery driver and I'm always looking for directions on the map. The car belongs to the company I work for. He stated because of a new law, drivers are no longer able to use the phone while driving. So he went ahead and cited me.

Is it true that a new recent law completely prohibits the use of wireless devices even for directions?
