I try to use passcode, but after about 2 days, I get irritated w/ entering a passcode.
I do, however, reactivate that feature if I'm going to a bar or a crowded place, just in case. If I'm at home or just with a few friends, I don't typically bother.
I DO want Apple to implement something to where people can not just switch the find my iPhone feature off.
That should require a passcode for sure. Preferably longer than 4 numbers. If someone knows about that feature, it's useless and they'll just turn it right off. I want to be able to prevent them from doing that without having a passcode on the device. You should need to type in a passcode to be able to turn it off at all.
