Sony Ericsson and the extreme sports brand Billabong have entered into a partnership, which will bring the Xperia smartphones closer to the adrenaline junkies, who are fans of the popular Australian clothing and gear company. The first product of the partnership is the Sony Ericsson Xperia active Billabong edition.

There is no difference between the newcomer and the tough as nails, regular Xperia active, which we came to like quite a lot, save for the Billabong branded back cover and some software additions. The latter include exclusive Billabong screensavers, preloaded videos, and an app to keep you up to date on surfing news.

Fans of the Sony brand gather around, because now you have got yourself a theme song on which to cheer your beloved phones.

Well-known Xperia fan and YouTube user Domothy85 has created a third music video to celebrate the Sony Ericsson Xperia line-up and who knows, maybe attract new Xperia owners. The lyrics are really catchy and combined with the New Jagger melody by Maroon 5 it could really be worthy for your daily music playlist.

Sony Ericsson ST25i "Kumquat" has emerged in a spy photo and it looks, well, quite familiar. The upcoming smartphone looks a lot like the highly anticipated Sony Xperia S flagship, which got announced at CES this year. Its specs however, have been toned down a bit.

The device is rumored to feature a dual-core CPU, clocked at 1GHz and a 5MP snapper. The screen is reportedly in the 3.5" range, and has FWVGA resolution.

Sony Ericsson Teased us with a subway photo of the Xperia Arc HD, we have got what appears to be the back, this connected with the rest of the leaks showing off the entirety of the device. What we saw earlier today was photos of the sides and the front of the device, it being a generally candybar-looking smartphone with a lovely stylish metallic strip along the bottom and black plastic around the edges. Now from Sony Ericsson Germany we have got the back in full HD, nearly.

This device is what Sony Ericsson will almost certainly end up calling the XPERIA Arc HD, also thus far codenamed Nozomni. The smartphone has been tipped to have a 1280 x 720 display, this putting it up in the Galaxy Nexus and iPhone 4S range for superior resolution, and Android 2.3.6 Gingerbread will be pre-installed on it. Inside you willl find a massive 1.5GHz dual-core Snapdragon MSM8660 chipset and absolutely no expandable memory. And a beast 12-megapixels camera too.
