iPod touch Draw Chinese Characters to look it up in a dictionary

Hey guys,

I was wondering if there was an iPod Touch app where you can draw chinese characters onto the screen and the program would recognize your strokes and tell you what character you drew and tell you its definition.

I looked around a bit, and found this app, but it says that it requires the iPod to be jailbroken.

So I am looking for a program with the same functionality as that, but preferably something that does not require me to jailbreak my iPod. I have already looked at Apple's App store but couldn't find anything that would let me actually draw the characters.

Thanks very much in advance .
