Android-maker Sony Ericsson has filed for the XPERIA Ion trademark for what is speculated to be a variant of the company’s codenamed Nozomi smartphone, which boasts high-end specs. The LT28at model is believed to be a variant of the rumored Nozomi phone with a 4.55-inch display with a 1280 X 720-pixel 720p HD resolution screen.
The trademark was originally filed on December 13, and it’s unclear what name the phone may be released under. Previous speculations had it that the Nozomi phone would be branded as an XPERIA Arc HD handset.
The device may be introduced by the handset maker as early as CES this year, or a year after the XPERIA Arc was introduced at CES 2011.
In addition to the high resolution screen, the LT28at is believed to have a 13-megapixel camera, giving it the most megapixel of any phone released so far in the U.S. The previous title went to Nokia with its large 12-megapixel camera sensor and Carl Zeiss optics on the Nokia N8, which also had a Xenon flash.
The LT28at is rumored to also support 4G LTE alongside HSPA+ on AT&T’s carrier network.
