I just lost my iPhone 4. I've been trying to call it but it goes straight to voicemail which makes me think that someone has picked it up and turned it off. I just started with ATT for this phone. I've never had them before. I tried to call them and ask for advice but the directory system just wants to turn my phone off which I'm not so sure I want to do in case I want to try calling it some more in hopes of getting someone who would return it to me. Anyone have any advice for me? I'm freaking out.
