While Sony Ericsson has yet to release the XPERIA X1 to the awaiting public, they have recently announced the availability of a free SDK tool for the XPERIA X1 which will allow developers to take advantage of the X1’s Panel Interface. As for the Windows Mobile-powered phone itself, they’ve assured the public that they’re on track for a 4Q release. 

So, aside from the promise that it’ll be available this year, the release of a SDK paints a pretty interesting picture ahead for those waiting to get their hands on the XPERIA X1. With the SDK, 3rd party apps can likewise utilize the Panel Interface and will not only be limited to Sony Ericsson developed software. This way, you’re almost guaranteed that the whole user-experience in the X1 will be completely unique as opposed to other Windows Mobile-running devices. That is, povided of course, if developers will download the SDK tool first and use it on their apps. 

Unfortunately, in the greater context of things, these are all just empty promises until the XPERIA X1 is finally release. We’re keeping our fingers crossed that they’ll keep their promise of a 4Q release.
