What is this strange icon showing up?

[Watabou]

There is a a strange icon on the top next to where the battery is. It just popped up right now. I don't know what it means. It looks like a phone with some blocks underneath it...

Here are some screenshots, anyone know what it is?

Haha, I saw that, but I wasn't sure

How does that work in an iPhone?

The real question is what is that "3G" icon that is in the top left? I've heard that is rarely seen......
