I have never done the "wire trick". When I originally got my phone, it had the HBOOT 1.45.0007, I did S-OFF with Revolutionary, rooted, unlocked, and all was well. When the newer radio (11.59.3505.20_2) came out that also updated the HBOOT to 1.45.0013, I was told it would revert my phone to S-ON, but I don't think it did. It did update the HBOOT to 1.45.0013. I then had to relock the phone, go to HTCDEV and use the HTC unlock tool, then I re-rooted the phone. So, I've been HBOOT 1.45.0013, with radio 11.59.3504.20_2, and I'm S-OFF, unlocked, rooted, without ever doing a "wire trick".
I don't know the technical details. I just know that my phone originally had 1.45.0007, now has 1.45.0013, and it is S-OFF and unlocked. I never did any "wire trick". When the new radio came out, there was lots of discussion about what to do to maintain S-OFF. I followed those discussions intently. I'm sure if I went back through the archives here on XDA I'd see where it was done, but I don't have the patience for that right now.Wow, to the best of my knowledge this isn't possible as the s-off part part of the .07 would be due to a patched hboot, that just ignores the security flag checks. Flashing another bootloader would erase the old one which means erase the patch. Radio s-off is much lower level and flashing firmware would not return to s-on no matter the firmware flashed. So correct me if I'm wrong here, but isn't the rev hboot just a patched bootloader? Just doesn't make sense how flashing a new bootloader and unlocking the phone would keep the radio secure flags turned off...
