Sony Xperia S and Xperia ION smartphones announced

The first Ericsson-less Xperia devices will arrive this Spring

Sony breaks free of the Ericsson shackles with its first smartphones released solely under the new Sony Mobile Communications company

The Sony Xperia S (pictured) is an Android 2.3 device (upgradable to Ice Cream Sandwich eventually) and will come to the UK in March boasting an iPhone 4S-like design, with squarer edges than many of the previous Sony Ericsson Xperia devices.

These will be Sony's first new smartphones since it acquired complete control of the Sony Ericsson brand during a star-studded keynote address at CES 2012.

During Sir Howard Stringer's speech, which starred Will Smith and Kelly Clarkson, the company revealed the Sony Xperia ION and the Sony Xperia S will arrive in spring and come under the banner of the newly formed Sony Mobile Communications company.

Sony says the design is "iconic" and "minimalist" but the see-through ribbon near the base of the device is certainly unique

Sony says the Xperia S, which is a global phone, is a "HD powerhouse" will come loaded with a 720p, 4.3-inch screen that comes loaded with Sony's Bravia screen technology.

There's also a 12-megapixel camera with super-fast shutter speed that promises to eliminate shot-to-shot lag experienced when taking pictures on most smartphones. Videophiles can also shoot videos at 1080p or 720p. Under the bonnet there'll be a 1.5GHz Qualcomm dual-core processor and 32GB built-in storage

Secondly, the Sony Xperia ION appears to be a US-exclusive device on the AT&T network and will be Sony's first ever LTE phone.

Also running Android 2.3 the Xperia ION will also boast a 12-megapixel camera and the lens tech mentioned above.

Sony says its new devices will focus even more strongly on the Sony Entertainment Network services like Movies and Music Unlimited, making it easier to access all of your content on all of your devices. Both devices, like the Xperia Play, will come PlayStation Certified bringing classic Sony PlayStation titles to your Android smartphone.

We'll be checking out both devices when we get access to the Sony booth here at CES in Las Vegas.

Update: Three UK has announced it will be carrying the device
