Whited00r only on 1/2 apple devices with 1 laptop?

My little brother has an iPod touch 2G in his drawers and asked me if I could 'fix it' so he could install apps. I told him I'll see what I could do and I found a thing called Whited00r. I have an iPhone 4 and do not wish to install this software on my phone, and I was wondering if after installing it would be safe to uninstall it (it is unlikely that I will ever have to plug his iPod back into my laptop anyway).So I guess I'm asking if whited00r 6 is untethered and if installed, will it effect my iTunes in any way after uninstalling? I would use another laptop, but we only have 2 and both have an iPhone 4 on it, so either way I would encounter the same problem. Thanks in advance, 10 points to best answer as soon as possible.

No. There's no effect.infact i have ipod 1g and iphone 4s. I'm using whited00r in ipod. No problem detected. And yeah it is untethered. So go ahead. Don't worry.
