Whats going on here in my country (India) is the cops put your phone on tracking( they call it CDR here wherein your number is not blacklisted, instead, upon registration of a stolen phone's IMEI number, it is tracked down through IMEI number using the triangulation method). Now, my point is, I only had two hopes of getting my phone back
1) FindMyIphone (which is hardly of any use to me now even though my location services are on and the phone is in the lost mode)
2) IMEI tracking( which hopefully works), but thats where the problem lies. If my IMEI is morphed, how will the tracking take place! (Another wastage of resource!)
I have only heard about IMEI disablers/changers, they do exists for Nokia phones and other OS phones, but do they actually exist for iphone5! Ziphone is stupid, I dont think it works in real.
Whether the thief is tech-savvy or not doesn't concern me. They run a gang, and its their only way of earning money I guess. I have seen and heard so many phones gone into disarray and none of them getting tracked thru CDR, such an unsuccessful outcome only makes me wonder whether the police here are stupid or the thiefs are voraciously smart!
Now I believe, Apple should place an Apple ID restriction, upon activating the lost mode, the least apple can do is turn on the location services by default, lock the apple ID forever (so that even flashing the phone wont work), register the IP of the computer it connects to next and send the IP to the cops or the respective person himself. I am being too dreamy, but yes, seeing the resources they have, I think it can be put to practice.
My phone will be in the lost mode and I will keep on using apple's resources untill they allow me to, this idea can be efficient both in terms of resource utilization and positive outcome to a problem.
