IPhone stolen so how to wipe phone clean?

Someone took my phone yesterday and I see that if I go to iCloud online it says I can erase everything on my phone. Does that mean the guy won't be able to go through all of my personal things? All pics and phone number will be erased? It also says once I do that then my iPhone won't be able to be tracked anymore so that sucks. But I know I prob won't be able to find it ever again anyway. So what exactly gets erased when I wipe my phone clean through icloud? I would just hate some creep to get ahold of all of my pics and content info… And I don't want him/her to enjoy any free music lol

Yes, all content on the phone would be erased.No, the phone number can't be erased from a phone. It can be deactivated but you have to contact your carrier for that.
