Touchwiz 4?

[varucell]

So I have been trying to find this but can't seem to, does the charge run touchwiz 4. I thought it did but so does the galaxy s2 but it looks different on that phone

No the S2 is the first device running it "officially" but it has been ported to a number of other galaxy S devices and could make it's way to the Charge

What are the differences between TW3 and TW4? I haven't seen anything that sums it up quickly. And a lot of search results lead to developer forums.
