Neterlands first public GSM locator.
http://www.gsmlocator.nl/
All cell phone owners are publicaly trace-able. !!!!!!!!
*Note.
The site has some problems handling all the requests.
So i got a "Sorry we are to bussy right now, try again later today" because of there enormous success.
It went "on Air" today so there is much traffic from curious ppl at there first day. It'll probably stay slow for a few cos this locator is quite popular so to seem.
*note 2
The site is in dutch but you only have to fillout the number you want to locate and your own email address to where te result is sent.
So be aware
