This is nothing new and not iPhone related ONLY. There are always some people that are trying to capitalize from the naivety or inattention of others. The iPhone DevTeam rings the alarm on some scam sites pretending they have an unlock solution for firmware 3.1.3 and the new iBoot. They don’t have it, and jailbreaking/unlocking software will always be free. It even says so when you load them…
Regarding to our previous post, Sheriff Hashim did manage to crash the baseband and possibly find an exploit. But this does not mean that it is 100% certain a new unlock tool will be released. The iPhone DevTeam is conducting various tests, and if successful a new tool will be released. There is no estimated release date, and ( again ) it is not certain that a new tool will be released.
