Sorry Pibe for missing this post.
SKTools doesn't change your browser agent behind your back. In fact mine says the same thing and I just came off of a hard-reset, so I don't think that is your issue.
In other words Mozilla/4.0 is different from the IE 6.0 hack which makes your browser look like a desktop browser (and therefore, no "mobile" sites).
I hate that hack and have never used it myself so I would noticed if SKTools ever changed that.
So I'm not really too sure what to tell you for a solution...
