Less than one week after going on sale via its own e-commerce site, the 900MHz version of OpenMoko's Neo FreeRunner Linux phone has sold out, but don't despair yet as more are on the way.

The 900MHz GSM model of the phone will appeal of geographies, including Australia, where that spectrum is used.

In the US the 850MHz frequency is more popular.

OpenMoko founder Sean Moss-Pultz refused to release details of how many 900MHz units were produced and sold, but was pleased with the popularity of the new phone, saying people from "all over" are purchasing them.

"[Sales are] still more concentrated in Europe and North America," Moss-Pultz said.

He said the sell out is only temporary.

When asked when they be in stock and on sale again, Moss-Pultz said "I think within a few weeks".

"I'm traveling now, so I'm not 100 percent for sure."

So stay tuned Linux people surrounded by 900MHz GSM broadcasts, the OpenMoko will be back soon.
