Sony [Ericsson] looks to be sticking to the design trends set with the Xperia S for the rest of their 2012 lineup, as evidenced in this leaked image of the handset currently codenamed Kumquat. The Sony Ericsson ST25i may have a goofy placeholder name, but it carries the sleek styling that had us praising Sony’s newly unveiled handsets at CES. Also present is the clear bar housing the antenna of the device. Specs include a 3.5-inch display at 480×854, a 1GHz dual-core CPU, and a 5MP camera with 720p video recording. There is no info on when we might see the device launch, but we suspect Sony will have some things to show off at Mobile World Congress in February.
