user6447: I want to create a small position reporter for cars. I found some good GPS Modules with which i could collect data. But i'm unsure with what technology i should send the data.
A possibility would be to setup a service in the www which is feeded by the arduinos.
I want to track the data live. so i think GPRS should be the right choice ?
Or more better are there any shields which make this GPRS LOG and SEND as a package ? 
Which GPRS hardware would you use ?
Would you use something else?
Any hints are very welcome

user630: You can actually find all the information for what you want to do on the formal Arduino.cc website. They suggest a GSM shield:

But of course you can find many other GSM shields for purchase. Most of them works the same. Arduino.cc also offer a nice GSM Library, with which you can perform HTTP GET/POST queries to a remote webserver (visible over the web).
You can select whatever web server technology you prefer for receiving the data. Using NodeJS, PHP, MVC.NET or any other, you could expose a REST API to perform the update from the Arduino+GSM Shield side using HTTP. 
The web server then could analyze the incoming data and display it in any way you like.
