Sony Ericsson's purported "iPhone killer" will join its rival on AT&T, technology demonstrations suggest. Given hands-on time with the XPERIA X1 at CeBIT, one publication notes that amidst a collection of webpage tiles in the sample interface was one dubbed the "AT&T XPERIENCE," located in the center; there were also no references to any other cellular carrier. It is already known that the phone supports AT&T's HSDPA/HSUPA bands, essentially leaving no technical obstacle to adoption.
The X1 is expected to challenge the iPhone due to the use of a three-inch, 800x480 touchscreen, which is combined with a proprietary icon interface to mimic some Apple concepts. Aside from increasingly screen resolution, however, the X1 may also be superior due to 3G broadband, as well as a QWERTY keyboard, a 3.2-megapixel autofocus camera, and expandable memory via microSD. The phone will only be out in the second half of 2008 though, by which point Apple may have a second-generation device on the market. [via PHONE Magazine]
