Will sprint also have the 1 year iPhone warranty?

Long story short: I live 1.5 hours away from the closest Apple store. My iPhone suddenly won't even turn on, and I seriously need to get it replaced soon. I still have 6 months left on my warranty through apple, so here is my question:
I know if I go to apple, they'll replace my phone. But if I go to sprint, will they also replace my phone?

Ask them

  • Will the one year warranty on my iPhone camera damage? I didn't buy AppleCare, but my phone still comes with a one year warranty regardless, right? If so, does that cover like the blurriness of the camera lens? Like I did nothing to it, it just randomly starting taking blurry pictures and if you compare it to another iPhone you can tell the quality is different.
  • What pops up when Apple checks your iPhone one year warranty? Like besides if you still have it or not, like what shows up? They don't get anything like my phone info within my carrier (Verizon, T-Mobile, etc.), right? Or do they? And they check with your phones series number, right?
  • My iPhone power button is stuck and I have a full year warranty? Ok, so my iPhones power button has been stuck for awhile now and need to get a new one I still have my warranty but can't find the paper with all my contract stuff the day I got my iPhone can he look at like a serial number or something on my phone that shows I still have my warranty?
