Step One
Put your iPhone into recovery mode. If you do not know how to do this then you can follow this tutorial.

like the other poster that has tried this, i hit enter after pasting in my ECID and nothing happens... kinda frustrating because i'm really wanting to jailbreak and this is the only thing stopping me as i'm scared to go ahead and jailbreak the 3G(S) without this being done! can someone provide information as to why this could be happening?! thanks in advance!

So when I navigate to purplera1n.com it has a window's icon and a donate button. There is no longer a place to put in my number to get the file generated out... anyone else having this problem?

look carefully there still is.....just press your tab key couple time or highlight with your mouse and you will see it

it could be your brightness is set too low to see, but there is a box to enter your ECID right below the windows and mac symbol.

This article leaves a couple of things unclear: first, why is it important to get this? Before which software comes out, iTunes or iPhone OS? How do you get out of Recovery Mode, just plugging into iTunes if I recall, but there's no restore or anything, correct? Not that I distrust GeoHot, but why do i want to paste my private security key into someone else's Web site (if it's not a concern, why did you guys white out yours...?)?

Okay, the follow up article and the Dev Team's post make it clear. Easy enough to do, and done already here.

U do the same thing to take it our restore mode, hold it till it goes off hold the home button and it should work.

cuz duh... apple could track the user who made the video.. knowing your ID they can block you..... take the tin foil off ur head and just do it.... aliens are not coming for you....

I think I'll wait until I get word from the Dev-Team on whether this should be done or not. I mean, this won't harm anything, but I trust them more.
Dragonista - June 26, 2009 at 4:28am
im with you on this, im going to wait until more people and dev team has confirmed and approve of this i don't want to mess up anything to delay jailbreaking my 3GS
lucasbrizzo - June 26, 2009 at 5:23am
I did it... it only took 2 min and these instructions are exactly what I did, and I didnt have a guide.

Ermm. Geohot is more cleverer than any of the Dev Team, he unlocked the first iPhone ever, BL4.6 and helped with the iPhone 3G, so stop being afraid, Geohot is extremely trustworthy :-)
Draonista - June 26, 2009 at 8:38am
i went ahead and did it, these are the type of positive comments i was waiting for before i did this and after looking at the step it seems that there are no harm that could be done instructions were very simple and easy, thanks for all your hard work and hope the freedom of the iPhone 3GS is soon!

Also is this tutorial just for 3gs owners or also for rest of us (2g, 3g?).
Dragonista - June 26, 2009 at 7:25pm
i would believe its for the 3GS because all the other models are jailbreakable but yet i may be wrong, maybe for all 3.0 users good luck

hmm! this is so strange.. I don't feel comfortable putting my iphone info on a website I don't know! if it's so important why the don't release an utility that produce this important file Locally. not on their servers....

From iphone dev: "If you already have a 3GS phone and have already done a full USB dump or captured your img3’s signed with your ECID, then you’re in great shape." In other words they are telling people to do it. Follow iPhone Dev and Geohot on Twitter
