I've found several YP-U2J (not just YP-U2) MP3 players listed by Samsung support. The direct link to the support for the YP-U2JQB/XAA is http://www.samsung.com/us/support/owners/product/YP-U2JQB/XAA . The manual is here: http://downloadcenter.samsung.com/content/UM/200604/20060401094436140_YPU2J-USA-ENGLISH0.0.pdf . If this link doesn't work, start at the above link and the Manuals & Downloads tab. (You'll see a pop-up, click Send.)

Alternatively, start at http://www.samsung.com/us/support/downloads . Select Media Players under Mobile. Then select MP3 Players and finally the model. Then look for the Manuals & Downloads tab.

I hope this helps.

1. try entering null as password.2. try entering your username without @gmail.com3. Combine 1 and 24. Call yourself from another phone, answer, without hanging up press the home button, then menu button, settings, try to disable pattern-lock5. Call yourself from another phone, answer, hang-up, directly after hanging up start pressing your buttons like a madman for <30-60 seconds ending with your home button (might take a while to get the timing right). Go into settings and disable pattern-lock.6. Try the normal recover password routine from GMail.com
7. Perform a factory reset. YOU WILL LOOSE all not-synced DATA (SD card will be left untouched).
1-6 are possible workarounds, these doesn't work for everyone but can be worth a try to avoid factory reset. 6. is what should work but hardly never does. 7 - The factory reset always work
Added reference with some additional info, how to factory reset can be found there.Good luck!

No. It uses Samsung's own proprietary operating system.
