A document showing details of two previously unseen Sony Ericsson Xperia handsets — the X7 and X7 Mini — has been placed on YouTube.
The short clip was posted on YouTube on Friday and shows some specifications of the two devices which are said to be launching in the first quarter of 2011.
Running the Windows Phone 7 mobile operating system, the X7 — the newest Xperia device to surface since the Xperia X8 began making its way to the retail shelves on 7 October — is reported to have a 480 by 800-pixel WVGA 4.3-inch capacitive touchscreen display, 1.2 GHz MSM8260 Qualcomm processor and an 8.1-megapixel camera capable of recording HD video at 720p.
According to the information in the video, the device is also said to include an HDMI socket that will provide Dolby Digital Plus surround sound.
No sizing specifications are given in the video but the second handset — with the X7 'Mini' moniker — will also ship with a 480 by 800-pixel capacitive touchscreen display, though this one is shown as arriving with a 3.5-inch version.
Camera-wise the Mini is listed as a 10.1-megapixel affair, equipped with xenon flash, 3x optical zoom and capable of capturing 720p HD video footage.
Under the bonnet the X7 Mini is said to include the 1GHz Qualcomm QSD8250 processor and run the same Windows Phone 7 OS as its larger sibling.
Pricing and release details are currently unknown; Sony Ericsson had not responded to a request for information at the time of writing.
After several delays, an update that brings Android 2.1, also known as Eclair, to the Sony Ericsson Xperia X10 family began rolling out to some users at the beginning of November, according to an announcement on the official Sony Ericsson product blog.
In September, Sony Ericsson's chief technology officer Jan Uddenfeldt confirmed that the company had no plans to introduce handsets running on the Symbian operating system; instead, choosing to focus on the strengths of Android and Microsoft Windows Phone 7.
