The low-spec handset, which debuted in Spain last month, can be snapped up only on ZTE's official eBay stores on both sides of the Atlantic.
The Open is the first phone to boast the new HTML5-based software and arrives with a 3.5-inch 480 × 320 HVGA display a 3.2-megapixel camera, Wi-Fi, Bluetooth 2.1 and an FM Radio.
The handset is based on an 1.0GHz Cortex-A5 chip design with Qualcomm chips and also has a built-in A-GPS sensor
While, spec wise, the handset isn't even close to competing with the big guns, the expenditure is minimal for those who wish to have a nose around the browser-maker's new mobile offering.
Head on over to the eBay stores where there are limited qualities available, with 556 handsets sold in the UK and 402 sold in the US at the time of writing.
