track mogul via gps or lock lost phone (post lost)

[almighty]

so i remember a friend of mine showing me this neat trick with his phone, he can send it a text msg and lock it completely, also any phone numbers called outbound would be sent as a sms-email to him. i cant remember what phone this was on but would like to think it was a nokia Q-like phone. i would like to add similar functionality to my mogul and every phone afterwards. also i remember hearing about a program for symbian phones that would allow someone to send a text msg to a phone and the phone would reply back with its gps location on demand. does anyone have any clue about either of these setups?

silly me i ment prior to being lost.
