Device apparently features a 1.4GHz processor and 720x1280 HD display.
According to a new report, the HTC Opera UL will be the first official Facebook smartphone.
An unnamed "very reliable source" told Pocket-lint that the social network's first handset is currently in development and a benchmark test has apparently revealed the first details on the unannounced device.
The source claimed that the 'HTC Opera GL' is the name for the handset which is being developed specifically for Facebook, with the benchmark result said to have confirmed a 1.4GHz processor and 720x1280 HD display. The Opera GL purportedly runs on Android 4.1 Jelly Bean.
The insider added that the Opera UL has experienced several delays. However, it's not clear why the rumored Facebook handset was the subject of delays or how long the device has been pushed back for.
While Facebook has yet to publicly confirm plans for its own device, the social network has stressed its confidence in the service's mobile users, which exceeds 600 million.
