Mobiles Antitheft or Spy Software?

Hello to everyone!
Today we will speak about a software able to protect your mobile from being stolen or lost... Or maybe just another spyware able to track your (or not...) mobile anywhere on the world. This program basically work as always... You need to install it on the phone and it will be "totally" hidden. Guardian-Mobile will protect any application present on your mobile by setting a password needed to access them... For example, when accessing to your SMS in-box folder or contacts list. There are a lot of other interesting features like the possibility to managed your phone remotly from another device by sending sms with special keywords... This way you will be able to retrieve SMS sent and received, phonebook contacts, the list of calls made and received, localize and track the phone using the GPS and Cell-id. If someone try to change your sim card with a non-autherized one then the software will send you a message with the thief number, the cell-id, the country and area codes... On the website there are three version of the software, the lighter one is free so you can try it by yourself. As I always do, I suggest you to read my article on "How to find anything on the internet" maybe it will be useful... ;-) 

They claim the Guardian-Mobile to be an "advanced antitheft software"...
Maybe that's right but, what about if someone install this software on "another's mobile"?

Like I will ever accept a phone as present from now on... What about you?
