Folks over iHackintosh posted some interesting scoops on Limesn0w unlock by GeoHot. iHackintosh found a picture and video with an option to install "Limesn0w". It seems that it unlocks the 5.14.02 and the 2.10.04 baseband. After the abrupt release of Limera1n it could be possible, but there is no proof for this.
