How long does it take for sprint to unlock an iPhone 5?

I'm a new customer and would like to know how long does it take for sprint to unlock a phone for international use?

Who knows. As far as unlocking goes, they are the worst company out there. I'm a Technical Advisor for Apple and they constantly tell people to call us when they want to get their phones unlocked even though the only person able to unlock a phone is the carrier. I would probably get fired for saying this but if that phone is no longer under the 1 year limited hardware warranty that comes with the devices, just go to a 3rd party to get it done. All those little kiosks that you see in malls that sell phones typically have the programs they need to flash the device, which is almost the same thing an unlocking it

They don't. With Sprint, you pretty much accept it or go to another carrier.
