Welcome to the forums!!

Here's something to get you started. I don't know what version of the S2 you have but it looks like this one might work for all versions:

[APP]SuperOneClick v2.3.3 - Motorola Exploit Added! - xda-developers

I would read everything first before attempting to unroot though.
