iPhone 3GS with old bootrom. Valuable?

[baskie]

I've just discovered that my 3GS, which `I only use as a spare now, is the old bootrom. Least I think it is, it has [iBoot-359.3] at the end of the serial when looked at in System Profiler. Does this make any difference to it's value? It's a 32g model.

I ask because I recently picked up another 3GS, soley to try out iOS5 on. Now I've played with iOS5 I can sell one of them. If an old bootrom 3GS is more valuable obviously I'll be selling that one.

Of course, I might be mistaken, the 32gb model with the [iBoot-359.3] at the end might not be old bootrom at all, in which case I'm sure someone will tell me soon ;-)

[iYeow]

Yes, it is definitely more valuable. Old bootrom can always have untethered jailbreak

[baskie]

Untethered you say? Hmmm. So how would i go about doing that?

I've upgraded the other 3gs I got to try iOS5 on, and have it JB's tethered, but how would I do it on the old bootrom model?

I'd also need to preserve the bandband to unlock it. Previously for all this sort of thing I've used Pwnagetool, but I can't seem to find it for iOS5. Is it out there? If not, what else builds custom firmwares without touching the BB?

Thanks.

Restoring to custom firmware of 5.0 or 5.0.1 created by snowbreeze will preserve your baseband.

[baskie]

OK, so how do I make the custom firmware? As I said, I've used Pwnagetool a lot in the past, but can't seem to find it for creating custom iOS5.0.1.

Thanks.

Is your 3gs currently jailbroken ?

[baskie]

Yes, at 4.3.3.

[iYeow]

What is your baseband ?

[baskie]

05.12.01

I created custom firmware using Pwnagetool to get it to this point, that is 4.3.3 with 05.12.01.

I see you mention SnowBreeze above, I'm aware that is the Windows version of Pwnagetool, is that still correct? I don't do Windows!

Am I also correct in thinking that Redsn0w can't update your device with custom firmware, it can only Jailbreak the firmware presently on the device?

[iYeow]

You need to get to a pc and use snowbreeze 2.8b11 to create a custom firmware of 5.0, not 5.0.1. You don't need any aptcket verification.
Restore to this cfw of 5.0 created by snowbreeze.
Note : you cannot use redsn0w to create a No bb update cfw of 5.0 as this is not a jailbroken cfw.

[baskie]

I come out in a rash if I go near a Windows machine ;-)

Coming at this from another angle...

I can easily enough get the 3GS old bootrom unlocked, will only cost me £15, then I'm thinking I can just upgrade it to 5.0.1 and use the present Redsn0w to JB it, in much the same way as I did with the 3GS I picked up the other day to try out iOS5.

If I go this route, will Redsnow know the old bootrom 3GS can be JB'd untethered and so jailbreak it accordingly?

Again, thanks for all your help here.

[iYeow]

Yes, redsn0w will know it is an old bootrom and will give you untethered jailbreak.

[baskie]

Cool. might give that a try. Although, with the untethered due soon, I might just sell it!

Again, and again, thanks for all the help.

[iYeow]

No problem

[baskie]

Hi again.

I gave in and fired up a windows machine. My plan was/is to create the custom firware, bring it over to my Mac, then restore via iTunes. Snowbreeze has done it's thing creating it, but I can find it saved anywhere on the Windows machine.

Where would it save the custom firmware file?

Thanks.

D'oh. Ignore.

It should be on your desktop and it looks like this : sn0wbreeze_iPhone 3GS-5.0.1.ipsw
