Making a complete about-face from the trend toward Jumbotron Android superphones, the Xperia X10 mini and X10 mini pro are teeny tiny Android smartphones that will fit in small pockets and other tight spaces. The 3.1 ounce mini and 4.2 ounce mini pro are nearly identical with the pro version sporting a slide-out QWERTY keyboard.
We look at the unlocked GSM versions, the X10a mini andmini pro that have 3G HSDPA on AT&T's 3G bands. Like their big brother the Sony Ericsson Xperia X10, they run Android 1.6, but step down the processor to a 600MHz Qualcomm model. The 2.5 QVGA displays are capacitive and sharp, and the phones have GPS, Bluetooth and WiFi. Somehow, SE managed to fit good 5 megapixel autofocus cameras with flash into the design too.
