Someone stole my Neo Freerunner... :(

i'm assuming we don't want to brick it, because the thief is not very
likely to return the phone if it doesn't work, nor can we track it if
it isn't charged. He'(ll just dump the phone.

sending gps location (if available), cell tower information and SIM
card info (contacts, own number...) in the background to a predefined
cellphone number/upload it to a server or e-mail it (when internet is
available) seems to me the smarter choice.
