Sony Ericsson Sony Ericsson Kumquat ST25i spotted and snapped Tweet Tweet Comments Submitted by ericklamothe on Tue, 2013-11-12 17:34. This device was released last year as the Xperia U. I can strongly recommend it as a high quality and portable Android device. They are being phased out so you may be able to get one at an even better price now. The screen and the camera are of particular note. You have to login or register to comment.
