The latest update to Skype's Android application has just been rolled out and a big part of its goodie delivery is two-way video calling. Only a quartet of phones are supported right now: Google's own Nexus S, HTC's Desire S, and the Xperia Neo and Pro from Sony Ericsson, all handsets that shipped with Android 2.3 installed. We suspect the rest of the Android world won't be far behind -- Thunderbolt users will surely be wondering why they're not included in this first batch -- but for now it's just that fearsome foursome. Also included in Skype v2.0.0.45 is support for SMS messaging, which doesn't suffer from any handset restrictions
