I hate that Apple forces bluetooth and wifi on each day. I wish I could just turn it off and leave it off. Though the article did mention some phones still emit a distinct signal even with the bluetooth off. This is why I am still considering jailbreaking. I have not done it in a while but every once in a while am reminded that Apple really wants to lock down this device I bought. I would like to just have my phone do what I want. If I was jailbroken I could use RealCC and turn wifi and bluetooth off permanently not just for 24 hours.
