Id say it looks like a Glacier as well.
These go to 2 BG, anything larger is a hacked firmware on a smaller unit.
Honestly its not bad once you get a good set of ear buds and used to its quirks. Its the typical Ipod nano clone with a bigger case and screen, read that as cheap, cheaply made, and has no DRM (Allways a selling point to me.)
so you cant use Itunes, Napster, ect. Easy to brick, just flash the firmware.
Typical S1mp3 player, you will likely find the volume low, the video in AMV format decent after puzzling out the software for a week. And the Instructions lacking or in Klingon. The big plus on these units are the Nokia Cell Phone Battery vers the cheap battery used in the typical MP4.
