Sony Ericsson itself showed off its XPERIA X1 handset in a webcast the other day, but if you just can't get enough of it (and, judging from the number of comments the phone has gotten, plenty of you can't), you may want to hit up the::unwired website, which has an even more extensive hands-on video of a pre-production unit. Among other things, it shows that switching from portrait to landscape mode takes far less time than before, and the all-important panels seem to be a good deal more responsive as well -- the build being used is from early September, so it should be a reasonable indication of what the final software will be like. Hit up the link below to check out all sixteen minutes of it for yourself.
