I have an iphone with bad esn. What happens if i jailbreak it?

The iphone has a balance of 1000 dollars on it. It wasn't mine before but i want to keep it and connect it into my phone line. I have sprint. Does jailbreaking give me a nrw serial number? If not how can i get a new serial number?

Nothing can change the ESN. Don't ask us to help you STEAL.

Nothing will happen, it will still be useless as a phone.
you can't get a new serial number.
trade it for a working iphone on craigslist or email me

  • What really is a bad ESN? Does my situation mean I have one on my IPhone? Do I have a bad ESN? I fully own my phone. I got it through sprint free when I signed up for my plan and we also got a Note 3 for 100 bucks (we paid it upfront ) on the same plan. But we left our provider for AT&T. We did not pay our final bill yet but there's no charges at all for our phones on the bill. So if we fully own our phones, but did not pay the final bill yet (and is way past due in a collection agency… Unfortunately… ), do we have bad ESNs?
  • Should i buy a bad esn iphone and use it with gsm carrier? I wanna buy myself an iphone 4s from ebay. I live in bosnia and we only have GSM carriers. I noticed that verizon or sprint "bad esn" iphones are much cheaper so, should i buy that phone and unlock it to my network or should i gather more money and buy myself a new factory unlocked one?
  • Is buying a iPhone with Bad ESN bad? I want to buy an iPhone 4 or 4s but it says bad esn. I'm not going to activate the phone to any provider. I just want it for Wi-Fi for home use. Is it bad to buy it or okay?
