The G-Park application is great. You will be able to find your car by just touching a button. I tend to forget where I parked alot, so I am very happy with it.
I haven't heard about that feature. How does it work? Do you have to stop and enter information or something when you park, or is this somehow a part of the GPS stuff?
Very useful application of iphone, just by taking a GPS reading you can find where you have parked the car.
But do not forget to take GPS reading while you park.
else it will be a big trouble for you :P
