We haven’t heard much about Zingku since we predicted it would be hot in ’07 in the Mashable Social Networking Awards. However, Google now appears to agree with us, acquiring the company for an undisclosed amount. Currently, the Zingku site is closed for new registrations as the company moves to Google.

Google never seemed to do much with Dodgeball, another mobile social networking tool of sorts it acquired, so it will be interesting to find out what the game plan is here. Other recent Google news in the mobile space include the rumored Gphone, and the company’s bid on wireless spectrum in both the US and UK.
