Sony Mobile will release a new LTE smartphone in Korea this June according to a report from MT.co.kr. The article suggests that this phone will not be the Sony Xperia ion that was announced at CES earlier this year. Korea has one of the most developed LTE markets in the world along with Japan and the United States.
As things stand, this new model may be related to the Sony LT29i Hayabusa, for which a benchmark appeared recently. This handset is expected to have a +4-inch display with 720 x 1196 resolution implying no hard/capacitive buttons. It is also expected to be running the 1.5GHz dual-core S4 Snapdragon MSM8960 chipset from Qualcomm.
