Lost my iPhone on the bus

Before i lost my iPhone, i had the Find my iPhone App on it but then my iPhone went offline and so i couldn't track it anymore, but i want to ask, if an iPhone has been reset/wiped off and if someone turns it on will i be able to track it again or not? Or say someone tried to connect it to iTunes will Apple be able to tell me who and where?

Yes, one it's on, it on. You will be able to track it if they turn it on.
