They both come with a 2.55-inch QVGA touchscreen display, 5-megapixel autofocus camera with flash, 600MHz processor, WiFi Bluetooth, 3.5mm jack, UMTS HSPA connectivity, A-GPS and Google Maps, and Android 1.6 as its OS running in tandem with Timescape. The obvious difference between the two is the slide-out QWERTY keypad found on the X10 mini pro which should delight messaging aficionados out there. You can read the press release here.
The other new phone they introduced is the Vivaz Pro. Just like the X10 mini pro, this baby is a slightly modified version of its namesake, the Sony Ericsson Vivaz, and also boasts of a QWERTY keypad tucked underneath its touchscreen display. With the exception of its less powerful yet still very capable 5.1-megapixel camera, its specs are almost identical with the Vivaz. It'll ship with an 8GB microSD card, and will be available in black and white colored variations. The press release of the Vivaz Pro can be found here.
All three phones are expected to hit select markets across the globe sometime in Q2. Pricing of these new Sony Ericsson handsets, however, wasn’t part of the announcement.
