Today, Sony posted a teaser page saying, “Smarter is Coming.” I looked at the source code of the page and found that the image refers the X10. So most likely, this is the AT&T version of Sony’s Xperia X10. If that’s true, I’ll be pretty happy because it gives me better options to get a high-end Android phone on AT&T. Expect the X10 to come tomorrow and I’ll most likely write a post about it.
