How to check your iBoot version in Windows (or Mac)

Once in DFU mode, where do you go from here. You're now stuck with your phone in DFU mode and will have to restore surely? All just to find the bootrom version.
The info works though, I tried it on one of my other iPhones so thanks.

Why would you have to restore? You can get out of DFU mode by holding down the home button and the power button for about 10 seconds. If your phone is connected to your computer you'll hear a beep as when a USB device is disconnected. Then just press the power button and your phone will start up as usual.
And there are very good reasons one might want to check his iBoot version. People who bought iPhones around week 40 need to know whether they have the new version of iBoot, which requires a tethered jailbreak.
I thought you had to restore to get out of DFU mode. When ever I've gone into DFU mode and rebooted it took me to the recovery screen telling me to plug into iTunes.
I have never had a problem getting out of DFU mode by using the Home + Power keys to start a reboot.
Neither have I. But if kAoTiX has this problem, iRecovery should fix it. It's not like putting your phone in DFU mode actually erases anything.
359.32 or 359.3.2
I think it's the first one, anyway, if it doesn't have a 2 on the end, your good (359.3)
thanks lizard!
my friend just got a 3GS two days ago, i almost jb it until i read about the tethering restriction on the new bootrom. But the phone was purchased at ATT store, and when i checked it, it still had 3.1 installed.... if the OS wasnt updated to 3.1.2 i have a hunch maybe theres a chance it may be older stock, and have the older bootrom. heres to hoping... i'll look today.

Probably, must be a slower AT&T store to see 3.1 still
Did you check the 4th & 5th characters of the serial # to see what week it was made ??

Hi guys 
Just in case anyone's looking to this thread as a reference, the instructions didn't work for me. (I'm on WinXP, with a 3GS)
Specifically, when I went to look in the details panel, I didn't have a "Device Instance Path" as a drop down option. I had something close, "Device Instance Code" or something like that, but it didn't have the iBoot version information.
BUT I was able to use usbview (instead of device manager) to figure it out. USBview is one of the tools you use to get your ECID when you're using umbrella to generate a backup shsh in case you want to reinstall an old firmware after Apple decides it doesn't want to let you anymore.
I'm not sure if we're allowed to post links in this forum, so if you're looking for usbview, you can google for: "howto usbview ecid shsh umbrella" to see how it's used for iPhones.
Oh, and the Power+Home button trick worked just fine for me for getting out of DFU mode.

Links are fine as long as it's not pirated software.
In that case
USBview download link here: http://www.ftdichip.com/Resources/Utilities/usbview.zip
Instructions on how to use it come from the tutorial here:
http://modmyi.com/forums/3g-s-downg...gs-restore-verification-server-ecid-shsh.html
That is the display from Recovery Mode not DFU Mode.
While you have it, make note of your ECID # as it can be needed for some 3GS restores using SHSH.
Thanx Mate. I got iBoot-359.3.2
You can always sell that one and get a gently used 2 month old 3GS with old bootrom. I just picked up 2 pristine 3GS's with older baseband (for wife and I)

You can hold out for a non-tethered jb some day, but I'd do what others have done, sell and buy slightly used!
didn't work for me
didn't work for me, there is no "Device Instance Path" listed and i'm definitely in DFU mode. Refurb 3gs from Black Friday '09

Recovery Mode and DFU are different. The phone MUST BE in DFU mode not in Recovery Mode.
how can i tell the difference? I've followed the guide:
