This is something the Iphone has a new application with Zipcar which allows you to be able to make resevations with any nearby cars that you would like to rent. Also you will have the ability to unlock the car doors with your IPhon. I like the fact that these applications for these I Phones are getting preety endless it is no telling what the next application they will drop you may be able to know when a brand new car just entered the lot for sell, and you prolly are going to be able to buy the car without talking to anybody just doing this by pusing some buttons. To me this can get to make society to lazy if it gets to this point.
