SE-NSE Forums:

For a start, the above image is the latest picture taken of a X10 running Gingerbread. Now what is confusing with this image is that appears to be using the same kernel as the current Android 2.1 update, which would mean that the new range of Xperia phones (like Xperia Arc etc)  would still be quicker than having a new kernel for the phone. In fact one user claims that cos of the lack of a new kernel, that it is basically SE trying to release a custom ROM.

Then there is a youtube video of a X10 with Gingerbread:

It appears to be using the old UI for the Timescape widget, but then again since the video is so short it is very hard to form an opinion of the video. All we do know is that the person that posted up the video has said that that this will be out in a few weeks. Hmm. Ok, until we see the video below:

Now this looks a lot more official. Pity it is in chinese hebrew, but Im sure that this is pretty much what the X10 will look like once Gingerbread starts rolling out.

In any case, needless to say that for the update you will need to be running official stock SE software. And my tip to you is to run the generic kit for your region (or location, as thats what they are normally based on).  Thankfully, another user at XDA has decided to post most (if not, all) the kits available. Now Ive just had a look at the topic, and I suspect that this is old firmware, so it might just be worth using PC Companion or Sony Ericsson Update Service to make sure you are on the latest firmware, this way not making you too disappointed if you see a “new update”, and then find out it’s not the Gingerbread update that most people want.
