Just a heads up to everyone...
If you're a user of the Opera web browser, check out their wid=gets section.
They offer a widget called 'Blocked,' which is in the app store under the same name. I'm pretty sure the developers are the same, but I could be wrong.
It's basically the same application, but for Opera. If you're interested in Blocked (which is currently #35 in the App Store), check it out!
