What happens when you turn on a reported stolen iphone?

So my iPhone went missing and i reported it stolen… Got a new one sent wit insurance to replace it. Now i found my old one that was reported stolen and wanna turn it back on to get my pics out but i don't want them thinking i falsy reported it stolen to just get a new one… Its sprint so i can't just take out the memory card and if i call the phone insuarance place theyll prolly just want me to send it back but i don't want too lol so what will happen if i turn it back on even tho it has no service?

If your location settings is on, on or old phone they(phone company) will see where it is…

If your phone is disabled(no longer to text/call) if it just turns on, your fine

They look for the owner.

1. Nothing will happens
2. They able to track the phone and report to authority.

On/off Phone are trackable as long it is powered by battery unless you re using anti cell phone jammer.
