Can you flash an Iphone 5 from sprint to boost mobile?

My sisters birthday is coming in a few months, and I'm getting her an Iphone 5, but I have boost mobile. I know you can pay someone to unlock it or flash it. I just wanna know if after it's unlocked it'll be possible to connect to boost.

According to here:

http://www.sprintusers.com/forum/showthread.php?t=216823

it says that you can activate sprint phones with boost mobile

Yes. Once you unlock an iPhone it will work with almost All carriers.

Ways to unlock the carrier restrictions are:

1) Buy a pre-unlocked iPhone ($$$ expensive)
2) Charge someone to unlock it ($$ somewhat expensive)
3) Jailbreak and use ultrasn0w (FREE)

Not sure if ultrasn0w supports the latest iPhone 5 yet.

Good luck and happy birthday to your sister.

Yes, it's possible to use the phone on Boost even if you get the phone unlocked.
