Instructions on how to generate a unique certificate for your iPhone 3GS' iBSS using a Windows PC.

Apple has added a new layer of security to the iPhone 3GS called the ECID field. According to GeoHot when iTunes starts the restore process, they contact Apple servers to generate signatures just for your device. It's important you get these signatures for your phone before a new version of the software comes out.

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

Step Two
Launch the USBView application. If you do not already have this application you can download it here. It is a small free utility provided by Microsoft.

I am not sure you even need this step anymore with his new jailbreak. I did purplera1n and never even used those other files. So maybe they arent necessary.

On the site now is the new program does this mean that you can't generate a unique certificate anymore? Or what do i do now if i don't have it yet?? Please reply.

I tried inputting my ECID and I get no response from the website about downloading the file. I have tried pasting it in and manually typing it all in. After I hit return, I get nothing. I am 100% sure it's the correct number, it's 16 digits, it's HEX. WTF am I doing wrong? Anyone else having this problem?

Are you doing this with a 3G or a 3GS iPhone? This only works with the 3GS.
spartacus - July 2, 2009 at 9:53am
Of course my phone is the 3G S. I wouldn't be trying this otherwise. XP

I have tried to find the "iBoot" on the tree for usbview and it does not show up on my computer. Is there anything else I can try?

Great! works exactly as it says... however, it didn't mention how to exit from DFU mode - if you are stuck (like me), just hold power & home buttons for about 10secs and the phone should restart itself. Thanks guys!

I'm new at this iphone thingy. I'm confused, why does the ECID need to be entered into that website?

when i go to control v and paste into the website all i see it say is device descripto and i click enter and it says ECID must be a hex string.Can someone please help me thanks

Did you copy it directly from the USB view window? DON'T incude anything but the numeric string to the right of EICD. There are several numbers on that line, you only want what is from the space after the colon to the space that goes to the next element on that line.

worked a treat, if you having difficulty read it again you only need the data that follws ECID: Scroll to the right in USB View its contained in the long line of data, this is the only line which extends so far right, the ECID data is the hexadecimal immeiately following ECID: when your in the purple ra1n screen scroll to the bottom and click slighly left of center until the cursor appears in the appropriate field, its hidden black on black so not eassily spotted, paste your ECID data here and hit enter, this will open and file save widow, just save that file where you can find it for a purplera1ny day perhaps :o)
rvs007 - June 27, 2009 at 2:38am
I was able to get into recovery mode and get the ECID.. However, when I put the string into the purplera1n website, it doesn't return anything.. no file, no option to save or view... anyone has this problem?
Ericidle - June 27, 2009 at 9:14am
Did you hit enter after you pasted ecid into the field?
Rvs007 - June 27, 2009 at 10:40am
Ya I did. I just realized this is only for the 3GS... I was doing it for my 3G which is probably the reason why it won't accept the ECID and return a text file. I'll try it again when I get my 3GS which is backordered for now :-(
MerchantWireless - June 26, 2009 at 11:36am
Got it! Thanks again Geohot! I was in Boston a while back when you had unlocked the Iphone for the first time. You are the Man! I can't wait to jailbreak/unlock my 3GS!
