The IP4 unlock from @planetbeing for 1.59.0 was available 5 days after the jailbreak in august 2010, get your facts straight.
And of course you not accepting it does not invalidate the argument; factory unlock, BB downgrade, SIM interposers, IMEI unlock.
Like i said before there is hardly a need for unlock development.
Contrary to jailbreak development, which is actively worked on, judging from you posts you havn't been jailbreaking for too long, otherwise you would know it takes more and more time as Apple makes it harder. Also the devs are more tight lipped due to several leaks; shatter and the infamous premature ipad2 jb leak when some wiseguy made @comex's work public before it was finished.
Some people think they are entitled to a jailbreak as like right now! If it takes a little longer they assume all kinds of things, ussually accompanied by unnecessary accusations.
Patience is a virtue
