Hello, I've been searching forums and can't seem to find anyone who has actually purchased a Sprint iPhone 6 from the Apple Store at full price. I was wondering if it was unlocked similar to when purchasing an AT&T and T-Mobile phone at full price from the Apple Store. Many people have commented that they are locked, but that's only from what they've read or based on iPhone releases in the past. Wanting to hear from someone who has actually paid full price (not subsidized) from the Apple Store (not Sprint). Thank you.
