I set up Find My iPhone, but before doing so, I used the same email address for my itunes account to log onto Find My iPhone. Am I being charged for this? Or, if I'm on a MobileMe Free Trial for 60 days, will they start charging me afterwards, or will they ask me if I want to purchase MobileMe or not? I just want to be sure that I did this properly, that's all. Also, is there a way to set up Find My iPhone on an iMac? So that way, I can search for my phone through my computer, or is that not possible?
