Q: I lost my iphone

Hey everybody!

I lost my iPhone 4S. I tried to find it through the service "Find iPhone", but it seems, that my phone is unplugged.

I don't remember my Serial Number and another data, but I can log in to iCloud and other apple services

So what should I do? What would be the next step?
