Samsung’s U3 follow-up, the U4, already broke cover on a Korean website a few days ago, but that brief appearance unfortunately didn’t consist of much more than a low res image of the device. The folks at Tevo have now thankfully cleared up the situation a bit, however, with a slightly better pic and some actual specs. Apparently, this one will be coming in 1GB and 2GB variations only, each of which will sport a 1-inch OLED display, along with support for MP3, WMA, and OGG formats, and a handy sliding USB connector. No word on a price just yet, but you can pretty safely bet this one will be on the low-end of Samsung’s many offerings.
