Will Unjailbreaking Undo My Carrier Unlock?

    Hey everyone,

    I recently sold my 3GS (Telus Network) to somebody who was looking to use it as a replacement for a Bell Network phone. The phone was jailbroken on iOS 3.1.3.

    After agreeing to meet with a buyer, I wiped the phone of all my personal information and upgraded to iOS 4.3.5, un-jailbreaking my phone in the process. The phone had a baseband of 5.16.02.

    However, it being my first time selling a phone, I was unaware that I had to personally unlock the phone. I was under the impression Telus or Bell would charge a fee to unlock the phone themselves. I realized I was wrong when the buyer brought the phone back to me asking me to unlock it for her.

    I told her I'd need a day or so to work on it. I originally tried a tethered jailbreak of iOS 4.3.5 but I was having so many issues unlocking with ultrasn0w that, after a series of Google searches and endless syncs, I ended up downgrading the phone to iOS 4.1 with a baseband of 6.15.00.

    After jailbreaking the newly installed iOS 4.1 (BB 6.15.00) with redsn0w and using ultrasn0w to unlock the carrier, it finally worked. I replaced my Telus SIM card with the buyer's Bell SIM card and managed to connect to the Bell 3G network. Made a call and everything. So that's settled.

    However, the buyer wants a non-jailbroken phone. She's worried about security vulnerabilities and whatnot. My question is: If I were to un-jailbreak the 3GS by restoring the phone to 4.3.5, would this undo my efforts to unlock the carrier?

    Thanks so much to anyone who can answer this.

    If you want your iPhone to stay unlock with ultrasnow you need a jailbroken iPhone! Unless you go and call Telsus to factory unlocked it for you, but they might charge you.

    If you want to be a little sneaky. Unistall cydia.app leaving ultrasn0w installed. The buyer would never know. Just tell them not to restore. I personally would never do this but just a suggestion, again it's not the right thing to do, but a possibility.

    I was contemplating that, actually. Hahaha. The buyer is technologically unintelligent, to put it lightly.

    How would I go about uninstalling cydia.app?

    I can't remeber as it is a while since I did it but you can google "how to delete packages in cydia".

    Thanks guys, you've been incredibly helpful.

    One last question: Would uninstalling Cydia render ultrasn0w useless? I guess what I'm saying is: Is ultrasn0w's ability to unlock an iPhone tied to the existence of Cydia?

    This is such a bad idea. You should give the client back their money and sell the phone to someone else. You are potentially committing fraud by mis-representing the product you are selling.

    You are selling the phone with GPS not working and with the buyer not being able to update firmware normally. You are also claiming that the phone is not jailbroken when it is.

    I hope they find you and sue your arse.

    Do the right thing.

    You are lying to the seller and that's bad. Give her back the money and sell it to someone else saying that it's JB and they won't be able to update it.

    WHY WOULD A BUYER NOT WANT A JAILBROKEN PHONE?

    Just don't update and one will have jailbroken benefits.

    Your buyer at some point will try to update via iTunes and they're going to be one of those idiots who think their phone is bricked, aka unrecoverable.
    Unless you plan to be a jerk and not help the buyer, it's better to sell to someone who knows the situation with the iPad bb.

    WHY WOULD ANYONE WANT TO JAILBREAK?

    Jailbreak is not for everyone. There are reasons people need to update the phone (eg. app requirement, new iOS features). Moreover, the ipad BB on iphone cannot be update the normal way. Op has already said the buyer is technological unintelligent and it's very likely that she won't know how to do it.
