Things appear to be better for the Xperia X1. Sony Ericsson has launched the SDK for it which means software creators out there can start inventing new Windows Mobile applications for the handset.

The SDK runs on visual studio so it will be quite easy for developers to start working on new apps. Testing them won’t require an actual Xperia X1 phone since all testing can be done straight on the PC where the handset is emulated.

The SDK release should suggest an official launch closing in soon. From what we know, Sony Ericsson has confirmed a Q4 release without suggesting any actual dates.
