Not sure how long this has already been on sale for in some countries, but it looks like Samsung is quietly rolling out the YP-U2Z, a 1GB update of that flash-based YP-U2 digital audio player we saw earlier this year. No major surprises here, the YP-U2Z comes in black and white, supports playback of MP3, WMA, and OGG files, and has an integrated FM tuner, a 128 x 64 pixel display, a battery life of about 13 hours.
