VetVito's Sexier Mobile (6.1.1)

[billyman]

First of all, THANK YOU VV & all the other cooks that donate their time and skills to making our phones the devices they are capable of being.

I have read and read about flashing custom ROMs, but I must be suffering from info overload. What I can't seem to get a grip on is the whole Unlocking / Relocking part. I see titan_SPL_2.40-olipro.exe, Hard-SPL-MFG.exe, Hard-SPL-240-MFG.exe, Titan_Relocker.exe...

I read the thread at http://forum.ppcgeeks.com/showthread.php?t=9093, but the more I read it, the more confused I got.

Which one am I supposed to use?
Do certain unlockers work with certain ROMs?
Am I supposed to relock it after I flash the custom ROM?
Or can I leave it unlocked until I decide to flash back to a stock ROM?
What do I need to flash one of VV's custom ROMS?

I'm running the latest Official Sprint ROM (3.35.651.2)
Please advise and thank you in advance.
