Yeah it worked for me. One weird thing that I experienced though was I updated the iPhone from scratch on my windows side, and then ran Limera1n but it didn't work, I had to go back to my Mac side, restore from backup (But now I was at 4.1), then go back and run Limera1n again, I don't know why I had issues and I don't think it is that common of an issue but just something to think about.
