Facebook fans rejoice: the HTC ChaCha has now officially gone on sale in the UK.
It's certainly not the first handset we've seen to be given the slightly wearisome “Facebook phone” tag, but it is the first to feature a dedicated Facebook hardware button.
The ChaCha was first rolled out at Mobile World Congress back in February, but was clearly still a work in progress at that stage, as HTC refused to let it out of its perspex cage for us to have a closer look.
Fast forward nearly four months, however, and you can gawp at and fondle the ChaCha as much you like by heading down to your nearest Phones4U branch.
Compared with its smartphone rivals the ChaCha is hardly the mobile powerhouse, featuring a mid-range processor, 5-megapixel camera and limited 2.6in non-touch screen above a physical QWERTY keyboard.
But of course it's that dedicated Facebook key that makes the difference. Tucked away below the keyboard, the button glows blue when there's a Facebook-related action you could perform, such as uploading a photo or sharing a web URL.
HTC has also tweaked its Sense UI slightly to integrate better with the social network. The standard HTC clock, for example, also includes a Facebook status update feed.
The ChaCha has been slapped with a £299.95 pay-as-you-go price tag. Alternatively, it comes free on contracts starting at £20 per month.
