ITEADUINO tiny

Recently started messing with the arduino nano. still very new to programming but i feel like im catching on. however, my nano took a dump. i can no longer upload code onto it and the computer doesnt see it when its plugged in. I have this ITEADUINO tiny from imall.ITEADstudio.com and i have no idea what pins do what.. can anyone help me?

I have looked at the itead website, and there is a schematic of the device but for someone like myself who is very new to this, it made no sense. I have also searched the web but found very little information. If you have experience with the ITEADUINO TINY, please help.

What about the wiki? http://wiki.iteadstudio.com/Iteaduino_Tiny It seems to be pretty clear on what all the pins do.
