@Rachol : If I use auto-reply, IMH doesn't consider SIM change, right? Couldn't you anyway send email reports, and/or add an option which does auto-reply usually but falls back to a predefined number in case of a sim card change? Or the other way around : a number is set, but a command from another number overrides it and it goes to auto-reply? My scenario : I want to be able to use autoreply right after my phone is stolen, or if I loos it somewhere and have to use some friend's phone to find it. But a thief will most likely ditch the sim card pretty fast, not allowing me to activate reports cause I don't know the new number. It would then be good if the phone could send reports to my own number (operator deliver replaclement cards pretty quick, or at least mine does), or an other, as I wish, when I don't know if I'm very clear... what do you think? Another suggestion : the geolocation icon shows itself when the soft tries to get a location, it could draw unwanted attention from the thief. Could you hide it before locating, and restore it afterwards? Powatool does this, it allows one to remove statusbar elements (the button in the statusbar menu as well as any associated icons)
