Yesterday, we stumbled upon a new video of the Rachael UI that the upcoming Android-packing Sony Ericsson Xperia X3 was supposed to have. Well, the company launched the phone today and changed two things while at it: First, it’s now called the Xperia X10 (presumably so that it isn’t confused with the Nokia X3) and second, the Rachael UI has now been         renamed the UX (short for User eXperience), due to some legal loopholes.

Launched at an event in the UK, the early prototype of the Xperia X10 didn’t get the reaction we expected. Sony has upped the ante in the hardware department for Google Android phones with this new offering, throwing in a powerful 1GHz Snapdragon processor, an 8-megapixel camera, and a large 4-inch screen.

BlackBerry Tour

Reliance Mobile, India’s second-largest mobile subscriber and largest CDMA subscriber, today announced the availability of the BlackBerry Tour smartphone for its customers.

“The BlackBerry Tour smartphone is a world phone in a complete sense, with sharp styling that resonates well with the suave and well-travelled consumer who wants to be connected while on the go. With multimedia functionality as well as support for email, social networking and a wide variety of other mobile applications, the BlackBerry Tour takes mobile empowerment to the next level,” said Ms. Frenny Bawa, Vice President, India, Research In Motion.

The BlackBerry Tour features a chic black finish with chrome highlights surrounding its sleek design. It measures 112mm x 62mm x 14.2mm (L X W X D) and weighs just 130 grams.

It includes a large, easy-to-use, full-QWERTY keyboard in addition to its large 2.44-inch bright display (480×360 pixels resolution), which delivers the highest resolution available on a BlackBerry smartphone and displays pictures, web pages and videos with incredible clarity.

The interface on the camera is simple to use, and is controlled by the touch sensitive buttons on either side of the screen. They’re easy to use, but take a little getting used to. The camera has a rough matte finish with a 2.5-inch screen.

Just like the M600i, this one doesn’t feature any soft-keys, and you operate it using either the stylus or your fingers on the touchscreen. There’s also the three-way jog dial, which, thankfully, does away with the annoying protrusion featured on the previous phones. The screen itself is wonderfully vibrant and quite responsive to the touch, but is, naturally, a fingerprint magnet. We recommend slapping on a screen guard the second you open the box—the screen’s responsiveness will suffer a tad, but it’ll be worth it.

The keypad is completely revised, with dedicated keys for Contacts, Calendar,

E-mail and Home. The soft menu keys, however, are too small for comfort. The rest of the keypad is a delight—good tactile feedback, and key spacing is immaculate. The rubberised keys for volume up / down, push-to-talk and power are hard to operate, though.

The E51 feels peppy—it uses the same processor as on the flagship N95. With 130 MB of memory on board, you can do a lot of multitasking without the phone getting sluggish, and the memory can be expanded to 4 GB via the microSD slot (a 512 MB card comes bundled). The E51 runs on Symbian OS Series 60, and crams in lot of features besides the standard set. Most of these will go down well with executives—for example, the Advance call manager lets you manage incoming and outgoing calls efficiently. In addition, WorldMate, an application for frequent fliers, comes bundled.
