According to TechCrunch, GeeksPhone’s online shop, which is currently down for maintenance, showed ‘Out of Stock’ message next to both the developer phones just hours after they went on sale. Mozilla revealed two Firefox OS developer phones – Keon and Peak – back in January.

The Keon, which is the lighter version of the two, is priced and $119 and packs a 1GHz Qualcomm Snapdragon S1 processor. Featuring a 3.5-inch touch screen the Keon boasts of a 3MP camera, 4GB onboard storage along with option for storage expansion through MicroSD. In terms of connectivity the phone comes with a MicroUSB port, Wi-Fi and GPS.

The Peak on the other hand is comparatively powerful of the two and packs a 1.2-GHz Qualcomm Snapdragon S4 processor. Featuring a 4.3-inch qHD IPS touch screen, the Peak has an 8MP rear-facing camera and 2MP front-facing camera. With onboard storage of 4GB this phone also supports microSD card for extended storage capacity. In terms of connectivity Peak and Keon are no different. When it comes to pricing the Peak costs $194.

Developers will be able to test their apps on these developer phones giving them a feel of what their app will look like on an actual Firefox OS phone.
