im selling my jailbroken 3gs, what should I erase?

[eckndu]

im considering selling my 3gs, it's on ios4.0.1, i activated it in itunes with my sim card and my apple account, used jailbreakme.com to jailbreak and then unlock it.
i'v logout from the app store, what else should I erase, I count sell it as unlocked.

thank you

Im the paranoid type & would wipe it as clean as I possibly could & then some...

Everything, DFU restore and them re jb

unless you are a rocket scientist and have some secrets on there I wouldnt worry about it much. just delete your contacts, email accounts, logout of iTunes, delete your pics, and maybe even delete your apps, recent calls, voicemail, etc. you will be fine!

And if you don't have shsh saved for 4.0.1 you won't be able to restore to it.

Hopefully you've saved your SHSH with Cydia. If you have, then simply restore the iPhone to 4.0.1 and re-jailbreak with jailbreakme.com. If you didn't save the hashes, then you'll need to see if the phone is worth more jailbroken and unlocked. If not, then restore to 4.1 and let the new owner wait for the 4.1 jailbreak, if the new owner really wants a jailbroken iPhone. Check eBay for prices.

I personally wouldn't sell my iPhone unless I restored it. I'm paranoid and while I know where a lot of files are, I don't know all the places stuff is hidden.

what's shsh??
all I did was editing some host file in /etc/, im not restoring it anyway.

what about that erase all data option in iphone? will it un-jb it and relock it?

yes.

or more accurately, you will NEED to restore phone and rejb...

and if you don't know whether you have SHSH on file, open up cydia, it should tell you at the top what SHSH blobs have been stored for you.

 

[eckndu]

it says SHSH: iOS 4.0, 4.0.1, 4.0.2, 4.1
i think i'm done

In order to restore your iPhone, the firmware needs to be signed by Apple. iTunes connects to Apple for "permission" to install the firmware. This signature is device specific. When Apple releases a new firmware, they stop signing the older firmware. This "permission" file is your SHSH, called blobs or hashes. Cydia stores your SHSH on their servers and when you restore using an older firmware, you can direct iTunes to search for the "permission" from Cydia instead of Apple. This allows you to downgrade firmware. But if Cydia does not have your SHSH on file for the specific firmware you are looking to install, then you will not be able to install this firmware. When you open Cydia, at the top of the screen, it will say SHSH: iOS xxxxx where the x's are the firmwares that Cydia has these SHSH hashes on file. You can only install firmware to these OS versions, or the current Apple version (4.1). Since Cydia says 4.0.1, you can restore to 4.0.1 and then re-jailbreak with jailbreakme.com. You'll have all of your personal data removed.

It means you can restore to any of those firmware versions.
So if you want since you already edited your hosts you can download an official 4.0.1 ipsw and restore to it. After its done setup as new phone and not from any of your backups and then JB and unlock it.

that's great, thanks for the clarification. one thing: I also jb it while it was on ios 3.1.3, how come that firmware version of shsh isnt on cydia's file?
quick edit: that's because I didnt use cydia's host to install that firmware, right?
