Sumit Malhotra, Global marketing manager for Xperia X10, has answered some questions about the device on the Sony Ericsson Product Blog.

Here’s what he had to say:

One of the benefits of using an open operating system is that we can tailor your phone to your specific needs. As an example, there is not a document editor preloaded, but there are and will be free and premium applications available in the application store.

Now to your questions. I haven’t been able to answer all of them at this point but have tried my best to get to as many as possible.

* Will it have multi-touch in future updates?
Xperia X10 has a capacitive screen. It does not support multi-touch functionality at launch, but is considered for the future.

* What’s a scratch-resistant screen?
Xperia X10 has mineral glass to prevent easy scratching and fingerprint coating.

* Is it based on OpenGL 1.1 or 2.0 for games and other stuff?
Xperia X10 supports Open GL 2.0.

* What is the size of the battery?
It is 1500mAh.

* How many colors does the screen support?
I noticed the confusion in the communction around this topic, but the correct number is 65,536.

* Will the X10 receive Android 2.0 update (for those who bought from the initial batches with Android 1.6) ?
The UX platform used for Xperia X10 will evolve to Android 2.0 over time.

* What would be the camera like?
We’ll try to post a tutorial video of the camera interface within short, but in short it’s quite similar to what’s seen in our earlier touch screen phones like Satio, X2, and Aino.

* When will this be available in the UK?
X10 will be available in selected markets during Q1 next year. We will get back with more details as to more exact timing and where.

So there you go, confirmation that an upgrade to Android 2.0 will come and that the device will support multi-touch when it does.

Cheers,

Mik
