Can mobileme find my phone when it is turned off or on airplane mode?

No. When the phone is off or in airplane mode, there are absolutely no signals or connections, making it impossible for mobileme or anything of the sort to connect to your phone.|||No..the phone must be on, in it's normal setting... It must be able to "ping", in other words send and receive information from satillites...|||It also has to be connected to a wifi signal. (unless you have 3G ofcorse)
