iPhone 5, iOS 8, get all my information on my icloud
how can I retrieve the numbers they called so I can locate the person that stole it?
You can't but what you can do is try and locate the iPhone > https://www.icloud.com/#find
The only way is try to locate your iPhone if the following conditions are met:
1. iPhone is NOT off
2. iPhone battery is NOT dead
3. iPhone has Internet connection
4. Find My iPhone is activated before the lost
Use https://www.icloud.com/#find to locate.
Only your carrier can tell you what number was called.
