It has been rumoured to death, so it's with some relief that we tell you that the HTC First has finally been given the official launch.It's a Facebook phone, but not the only one. With Facebook Home being offered to other smartphone users, it isn't the exclusive Facebook hardware we once thought it was. But it does have one big thing on its side - price.You see, HTC is selling this phone (initially) in the US for $99, which works out around £65. Of course, we're not stupid enough to presume that the price will be maintained in the UK, but it should be an affordable option. In fact, it could be the most affordable 4G phone so far, with EE offering this as an exclusive from the summer. You can sign up now for updates, although EE is being careful not to give out a UK price just yet.As for the phone, it's the mid-range affair we expected, with a 4.3-inch 720p display, five-megapixel rear camera, 1.6-megapixel front camera, 1GHz dual-core processor, LTE connectivity and Android 4.1.2 Jelly Bean for the operating system. You also get 25GB of Dropbox storage, too.But that's the secondary story really. The big selling point here is Facebook Home, which allows you to bring Facebook updates and notifications to your lock screen, with easy access to other Facebook apps from the screen too. It's the kind of software you'll love or loathe, depending on your love of Facebook. If you want to find out more about it, check out the details here.
