Can I use my blacklisted iPhone 4s on another Carrier?

It is a at&t Carrier iPhone 4s. Its been blacklisted on the at&t network since I lost and assumed it was stolen. I wanted to know if I can jailbreak it and use it on another carrier such as virgin mobile? Or because its blacklisted with at&t can it never be used on a network agian?

You're special. If you really do own it and are the original owner, take it to ATT and they might be able to get it off the blacklist. It's hard to do but that would be the easiest and cheapest starting point. Otherwise you'll have to buy unlock software to do it. Best luck.
