My buddy was going to check out a website on his phone (url wont be disclosed) when he opened up the default “Internet” app and cleared out the address bar and typed “http://www.re” with no quotes, the auto complete came up as http://www.redtube.com this is not a site he has ever been too on his phone.. To confirm this wasn’t just by chance I grabbed my phone and attempted to recreate the issue.. it did the same thing on mine..

For the record, it doesn’t appear on my default browser, nor xScope, using the BuglessBeast rom on my Droid… Still…. be cautious out there.
