Relock phone & flash stock rom before exchanging?

[AceszHigh]

I'm sending back my diamond to sprint today, because they just sent me the pro in exchange. Do i need to relock it and flash back to stock ROM...does it matter?

Yep, at least it can. It's possible that if they see you've changed the OS and whatever else, you've voided the warranty, and they can then charge you full price for it

Thanks, I figured as much. I relocked it, but when I go to the bootloader screen it still has "security unlocked" at the top of it. Is that a problem..?

No.
Read the tutorial again and you'll see that it always says that.
