.37 error 202. Why wont my sprint tp unlock??

[doitlaynstyle]

So I am trying to unlock my tp. I am getting the error 202. It is connected. active sync works. I have been reading a few things here and on other forums. what is sspl? i read that you have to be running sspl to get a spl to run? what the help is an spl? I am so confused. Its not like I haven't done this before. I updated my old phone to win 6.1 before I got the tp. I know how to follow directions. I am not computer illiterate. so a little info
rom is the 1.03.15f
the unlocker recognizes the rom version IE communicates with the pda then gives the 202 error saying it cannot comunicate with the phone.
I want to update the phone to win 6.5. also the version I want is the mightyrom but their site says they are in the changing room. any ideas as to whats up with that? also I never saw this question answered. if you unlock your phone and update the os, do you have to relock the phone?
