actually the code to check ECID is in ipod2g bootrom as well, but the actual sigchecking depends on where the ECID tag is placed in the img3. But interestingly they don't check the TYPE tag in either ipod2g bootrom or 3gs bootrom. --[[User:Posixninja|posixninja]] 15:24, 29 July 2009 (UTC) |

I don't think every iPhone/iPod touch has an ECID -- Isn't it only a 3GS thing? Iemit737 06:01, 27 July 2009 (UTC)
Put your iPhone or iPod Touch in Recovery Mode and look at the USB section in the System Profiler (if you're on Mac), then click on the "Apple Mobile Device...". In the detalis section (below the devices list) you will see a lot of IDs (also incl. the ECID).
But, it's very good question! I think that in spite of the fact that ECID is present on all devices, only on 3GS it is sigchecked on the bootrom. rusmac
When you say it's sigchecked by the bootrom - you mean the DFU mode of it? Not the normal one that's vulnerable to 24kpwn? Iemit737 09:07, 27 July 2009 (UTC)
