Sony Ericsson has just added a new device to the Xperia line of mobile phones, the Xperia acro. This handset is designed specially for users in Japan and packs in a 1GHz Qualcomm Snapdragon processor, and Android’s Gingerbread 2.3.

That’s not all. The phone also has an extra wide 4.2” screen, an 8.1 megapixel camera with Exmor R for mobiles, enabling users to capture low-noise, high quality images and HD video (720p) and there’s also TV-viewing, a mobile-wallet and more. Lucky Japanese.

The PlayStation Phone/Xperia Play has surfaced several times now it isn’t done teasing us since it has now surfaced again on a Chinese site. According to the latest leak, the phone is confirmed to feature a 1GHz Snapdragon processor and a Qualcomm Adreno 205 GPU.

It looks like the phone will feature a 4-inch 854 x 480 pixel resolution display, a 1500mAh battery, 5-megapixel autofocus camera, LED flash, microSD card slot, microUSB port and a secondary mic for noise cancellation. We can’t wait for this one to become available.

Sony Ericsson has started the first wave of Android 2.1 upgrades for the Xperia X8. Some of the mid-range smartphones will get the upgrades today and this should be followed by a “gradual” rollout to every carrier and country that supports the X8. We don’t have a solid timeframe since it depends on approvals from each carrier.

Some additional Xperia X10s are also getting the upgrade. The X8 updates are the same as for the X10 mini and mini pro, which didn’t get the full-size X10′s 720p video recording but did add support for media sharing with TVs, new versions of Sony Ericsson’s custom Mediaspace and Timespace layers, and the updated app and compatibility support inherent to Android 2.1.

We’d been hearing some murmurs about Sony Ericsson’s Xperia X10 mini, but it’s the X10 mini pro that’s a surprise. They are nearly identical except for launch colors. The mini ships in black, pearl white, lime, pink, red and silver, while the mini pro comes in just black and red flavors. There’s also a bit of a size difference, and the pro features a QWERTY keyboard.

They run Android 1.6 on a 600MHz Qualcomm MSM7227 and will ship in both North American and global 3G variants. Some other features include quad-band EDGE, WiFi, Bluetooth, and they come with a 2GB microSD card.

Among the many product announcements released by Sony Ericsson today the most significant has to be the release of the new XPERIA line by introducing the XPERIA X1. The new XPERIA brand marks a new era for Sony Ericsson in mobile devices, with this sweet-looking new model featuring a whole host of communication mediums, driven from a touch screen and full-QWERTY keyboard and riding on Windows Mobile 6.

SE calls the design of the X1 an “arch slider” as it slides up to expose the full keyboard with a large 3-inch VGA display on top. The impressive list of features continues with a 3.2 megapixel camera with auto focus and video, a microSD slot and communications via Bluetooth, GPS, Wi-Fi, and quad-band GSM/EDGE, and 900/1700/1900/2100MHz UMTS/HSDPA/HSUPA.
