Unfortunately, unlock iPhone 4S with ultrasn0w is not possible too, as ultrasn0w only support some basebands on iPhone 4 and iPhone 3GS. No one of iPhone hackers announced about any updated version of ultrasn0w. By the way you have to know that finding an exploit to ulock iPhone 4S became more difficult.
