Returning under warranty, what do I need?

[dshosu]

First off, I have searched extensively for the answers to these questions but I'm either not searching for the right things, searching in the wrong places, or it's not here. I'm assuming it's one of the former, never the less it's not like I didn't try. I'll keep looking though and update this post.

Anyway, I have a security and SIM unlocked Sprint TP2 and am going to be returning it under warranty today. What do I need to do?

1. I re-flashed the stock ROM from here.

2. Re-flashed the stock radio from here.

3. Then I need to re-lock it with the HSPL re-locker from here, but that's the absolute last step.

?. What do I do about the SIM unlock? does that matter? do I need to re-lock it? how?

Thanks to all those that can help!
