Having only just passed through FCC certification, it's a little surprising to find Sony Ericsson's new mini Xperia headsets on sale so soon, albeit only in Taiwan at this time.

The new Xperia Mini and Xperia Mini Pro are both minature Android based phones with their 3-inch screens. The Pro includes a slide-out QWERTY keypad, but is otherwise much the same as the non-Pro model.

Quickly running over the specs on tap here, they use a 1GHz Qualcomm QSD8255 SoC with Adreno 205 graphics, 512MB RAM, 320MB storage space (hmmm, bit small Sony?!), 480x320 3-inch display, 5MP rear camera capable of 720p video recording, 802.11b/g/n WiFi with DLNA support, Bluetooth 2.1, HSDPA at up to 7.2Mbit/s speed and HSUPA speeds of up to 5.76Mbit/s.

The phones both run Android 2.3. With the Pro's slide-out keyboard, it is the heavier of the two at 136g (measuring 92x53x18mm), while the standard Xperia mini weighs just 99g and is a smidgeon smaller at 88x52x16mm.

To get an idea on pricing, they're now shifting in Taiwan at NT$7990 (about $277) and NT$8990 (about $311) for the mini and mini Pro, respectively.
