So my girlfriend is pretty indifferent about updating her iPhone, and is still on 4.0 (not jailbroken). Once the new lineup is released, I'll be getting the new one and giving her my iPhone 4. We would like to get the best value for the 3GS, so I was wondering if we could jailbreak and unlock it before selling it. Obviously she has not been saving her SHSH blobs, so would it be impossible to securely wipe the phone without updating the software? If so, she may as well update to 4.3...
 
Just make sure to use pwnagetool to update. You have a perfect phone there if you don't update it poorly.
 
Now that Apple is only signing 4.3, that's the only version you can restore to. At 4.0 OS and 5.13 baseband, you can JB and unlock it which should bring higher resale value. You will have to manually go in and delete her personally info.
 
So if I were to use pwnagetool to update, would there not be a way for me to restore the phone without having to erase everything manually?
 
Unlock it and throw it on eBay and make sure to include international shipping! U'll be surprised for what you'll get.

That would be great, I'm just still trying to figure out how to restore it after jailbreaking, without SHSH blobs.

Also, from reading the stickied flowchart, it looks like I would need to use jailbreakme.com? The phone hasn't been jailbroken before, so apparently it isn't eligible for pwnagetool?

I agree, ebay is the way to go at this point. or craigslist.
But I disagree about international shipping. I guarantee people in like Nigeria will be emailing you about money orders and such :p

You dont need to be JB to use pwnage.
And you dont need to be JB to start saving your SHSH blobs.
Download and run Tinyumbrella. Maybe you'll get lucky and still save the 4.2.1 blobs.
And then you can restore to custom 4.2.1 JB ipsw created with pwnage so you can maintain your unlockable baseband.

Thanks for your help. Unfortunately Tinyumbrella's site says 4.2.1 signing is closed.. oh well..
 
Its odd how they closed the signing but technically the latest version for the general public is 4.2 right?
