iPhone 5 help

I got my iphone recently but i'm confused on two things;

Firstly, when I got my phone there were two reminders already on the reminders app, 'eBay iPhone' and 'Apple tv'. Is this the same for anyone else?

Also, I've got the rattle near my camera and have had conflicting views on whether that's meant to be there or not (even from apple employees). So is it meant to be there or not?
