Setting off a small smartphone nerd frenzy, Samsung launched a teaser page for the phone to let users sign up for information about the phone’s U.S. launch.

Samsung recently announced that it has sold 5 million units of the dual-core phone, according to the Yonhap News.

In addition to its super-fast core, the phone also boasts a 4.3-inch Super AMOLED screen, a front-facing camera and an 8 MP rear-facing camera.

The phone is expected to ship sometime in the next two months. Samsung is certainly stepping up its U.S. campaign for the smartphone in recent days.

This week, it sent members of the tech press — including yours truly — mini telescopes with the message “Keep watch for the next generation of the Galaxy S.”

Cute.
