Alltel touch pro sending back for replacement. I have a question

[Dutt1113]

I have an alltel touch pro and I have to send it back for replacement. I have already received the replacement. The phone I am sending back has spl 0.37.0000 and I have it relocked. I went into bootloader mode on the new replacement phone and it has spl 0.40.000. It is going to make any difference if I flash with the hard spl 0.37.cmonex on the replacement and back to 0.37.0000 with the relocker if need be, or will the relocker put it back to 0.40.000? Is it gonna make a difference if I relock the new phone to 0.37.000 since its not the stock locked spl of 0.40.000?
