About switching carriers

It doesn't work that way buddy.

 

Unless you bought at full price you signed a contract for service with Sprint. That means you are with Sprint for two years. Apple just sells the phone and provides the warranty.

Apple will replace your phone with the exact same thing you have. Even if you paid the full price and did not sign a contract with Sprint. Apple is only obligated to replace the exact model you purchased, nothing more, nothing different. You can always buy a new phone from Apple with a different carrier though.

But if you leave Sprint you will be charged ETF. Sprint has paid Apple in full for your phone that if you bought subsidized was not the full amount. Sprint, like all the other carriers will want that money back.
