Mobile Tracker feature in Samsung E 840- useless!!

I bought a Samsung E-840 mobile few months back and I had enabled the Mobile Tracker feature in it. In fact, I took the mobile primarily for the reason that it had the security feature of Mobile Tracker. I lost that mobile 15 days back. I have already filed a FIR along with the IMEI number of the handset. When I inquired about it, the police said that the thief must have got the handset formatted. Once the mobile is formatted, everything is reset and its settings are same as those when it is manufactured by the company. To my surprise, when i inquired about such software in the market, almost every mobile shop said that they can easily format that mobile. I just want to ask that if it is so easy to hack the Mobile Tracker functionality, then why does the company (Samsung) boast of it? It means practically it is of no use. It should be the responsibility of the company that they see to it that only the company authorized people can format it, otherwise what is the point in highlighting the feature?
