Hi all!
I've received today my new mp3/mp4 player and i'm already willing to flash it

It's a "J@By" Player, a clone of the last generation IPOD Nano, with 2 Gb of memory and support for Radio, Movies,Pictures... you can see it here:
Ebay
I'm noticing that transferring files from my HD is very slow and also that moving from a song to the next requires a second of delay... Also i think the installed software is not so well-built so i'm interested in firmware upgrading etc.
Could you help me anyway???
P.S. The chip is a Samsung one, my current firmware is 9.0.52
THANK YOU!
