Questions about selling iPhone 3G

#1
I just now decided to sell my old iPhone 3G. It looks like people are still asking about $200 on craigslist, so that works for me.

My question is about the best way to restore it. Right now it's running 3.1.3 and it is jailbroken. If I reset to factory will I need to install 4.0.2? Because I can't currently jb that. Is there any way to leave it as is and just get all my info off?

Thanks for any advice!

I've never done that but have you tried to just erase all content and setting from the general tab? Once you take the sim card out I would think they are left with just a jailbroken phone and that's it ,

I did this, but how do I remove my phone number from the phone? Or has this already been removed once I updated to iPhone 4?

Should I sell the iPhone 3G with 4.0.1 or should I restore 3.1.3? I have the tools and firmware to do this.

Well I tried to erase the data and ended up getting stuck in the Apple logo constantly rebooting. So now I'm stuck and need to restore. But I think I will wait until next week and just install 4.1.

That's when you take your sim card out, I did that with my 3GS and everything worked just fine. I would in my personal opinion restore to 3.1.3 and sell it that way, I'm giving the option to the buyer to update and take a chance on 4.0 since it's not working magic on the iPhone 3G. Once again that's my own personal opinion

Is it still stuck?

I read that as long as I delete all without iTunes, and don't connect to iTunes, that the phone remains unlocked and all personal data is erased. But, if I connect to iTunes, the iPhone will be locked to AT&T.

Are you saying I should connect yo iTunes and remove the sim or just remove the sim card? To downgrade to 3.1.3, I do have to connect to iTunes, though.

I listed my iPhone 3G, as is with iOS 4.0.1. I'll see if I get any hits. If not I'll downgrade it and relist it.

Oh no I was telling him to erase all content and setting, than remove the sim card, no through iTunes from the phone itself, that should delete everything personal from the phone, but mine wasn't jailbroken so I'm not sure if thats gonna be deleted, but you can always go to jailbreakme.com and re-install it, after that remove the sim card.

You should just leave the 4.0.1 the way it is. Now that's what i did and had no problems, I called the guy few days later and he was happy with the phone running 4.0.1 jailbroken and with tmobile

So leave it, but removed the sim card? Is this still an unlocked iPhone?

Leave jailbreak alone, erase all content and setting, make sure nothing is there when it's done like phone numbers photo iTunes info, check if it's still jailbroken if not jailbreak again, take sim card out and that's it. Now what I was saying is that I've never jailbroke my phone so I'm not sure if it's still gonna be there when you're done, just don't update to 4.0.2 and you can always go and jailbreak again before you sell

My iPhone is not jailbroken. I never said it was. Plus I can't check for any content without connecting to iTunes and creating a new iPhone. It now says connect to iTunes.

Ok Now you said you wanna sell your phone and just wanna make sure your phone number is not in it, by erasing all content and settings and removing the sim card you are good to go. There's nothing in there anymore you can sell your phone. That's what I did. Is that what you needed to know?

Hello---follow up clarification questions on What to do prior to selling my (non-JB and non-unlocked) iPhone 3G if I want to be as safe as possible about the data on it.
1) Do I need to do anything other than just clicking the Erase all Content and Settings button?
2) Do I also need to remove the sim card and not give it to the buyer?
3) Do I need for example, to follow directions on the 2008 CNET post and Jon Zdziarksi's post from 2008 on erasing the original iPhone?
4) Do I need to JB and unlock the phone to do any safe erasing of data?
