Sprint iPhones flashed to another carrier?

I have no idea where to begin. I HATE sprint. They are ridiculous expensive and the coverage sucks. I have an iphone 5, 4s, and 4. How do I go about flashing it to another carrier? Who do I contact?

You would have to contact Sprint. There may be some methods out there to unlock the phone but if you break your contract with Sprint then no other carrier will take your phone. You can also only flash it to another CDMA network, which in the US is only Verizon. There's no way to unlock it to Tmobile, ATT, or any GSM network.

Hope this helped!

If it is a new iphone4 and says sprint and you don't have an account with sprint, how do you get the cdma flashed so you can have verizon as a carrier

  • What means iPhone is flashed to Sprint? So I'm buying iPhone 5C from eBay and it says: "Bad ESN (which mean that it can't be activated on Sprint) and flashed to Sprint" my question is: What means "flashed to sprint"?
  • Can I use my sprint phone with another carrier if it isn't paid off? I current have a iphone through sprint but the plan is pretty expensive. I'm thinking about switching to boost mobile. Can I use my sprint phone with boost mobile even though i haven't paid it off with sprint yet?
  • If I buy an iphone used from another carrier ad buy a sim card from my carrier will that work? I have an iphone 4s with virgin mobile and I want an iphone 5 but all virgin mobile phones are so expensive! I looked on ebay for virgin mobile nano sim cards and they are only around 2 dollars. If I bought one of these sim cards and a used iphone 5 from another carrier would it work with my carrier?
  • How to activate my sprint iPhone 4s for another carrier? I had a plan with Sprint and I recently cut them off because it was too much for me, I have an iPhone 4S for sprint but I always wondering if I can activate it on another service? Is it possible? I wanted to activate it with Boost Mobile or with Straight Talk, that cheap prepaid stuff. I don't want to buy any prepaid cards and then not be able to activate it
