Works perfect.

All you need to do in your code is include mobile_device_detect.php and then the function mobile_device_detect() will return to you the device (Android, IPhone, ...) you're running on

Here is your solution:

after alot of search i think the simple way is to use a web service

This means no downloads, no installs, no hassles... just simple!

EDIT:

The web service is not available now, i recommend to use http://deviceatlas.com/ or http://51degrees.mobi/ (commercial) or if you look on open source look on : Best Open Source WURFL alternative
