yes...to run dfu mode u cant insert sim card inside...

Not many people are as good and as smart as you SIR....Congratulation on your success too. I believe you must be very PROUD of it. If you see the treats carefully, allot have failed when following the given instructions (from those given URLs) even though it has been posted everywhere. What was asked before is merely a favour from 'willing' users and 'Forumers' who has done it successfully and cleanly...Anyway,thanks for sharing your thoughts and exprience.

i LOLed at this.
have some effort. people here also do things over n over again in order to get it right. please BE CONSIDERATE.
and remember though, here is not Apple Customer Service. even Customer Service doesn't consult on unlocking and jailbreaking the iPhone.
i think the iClarified manual is not that hard. just follow step by step. even they got illustrations accompanied with each step. is it too hard for u?
mmm...before this i used winpwn but sometimes it tend to be buggy. at last i use a mac to do Pwnage.

and what amazes me, u haven't put here any situation that u encounter the problem. instead u kept complaining and complaining.

myb u can STOP complaining and start telling us bout problems u encounter. or start with DOWNLOADING THE FIRMWARE FILE first.

have a nice day.

(p.s: btw, some forumers here r glad to help if u meet them. it should be the most idiot-proof way, but only u can't get the excitement of accomplishing thingsfrom A to Z on your own. u can search around for some members here that r active on contributing help outside the forum. hope this helps)
