Websites showing up as visited, when I haven't been on the internet! ??

[toddandshelly]

I didn't have time to do anything besides check my Gmail, and phone messages today on my phone, however the browser history shows "history" for yahoo login (I don't have ANY yahoo accounts at all so I know I wasn't there), as well as a few other sites, when I hadn't been on the browser on the phone at all today.
I looked further back and it shows a ton of Yahoo visits, and it goes directly to the Login page when you click on it.
I'm confused since I never used my internet today, nor do I ever visit Yahoo...
What could be causing this? I am the only one that had access to the phone today.
