I'm not 100% sure of everything S-off achieves but i know by achieving S-off you can unlock the service locks such as unlocking the phone to be used with US GSM sim cards (such as AT&T and T-Mobile)

S-off will technically unlock all the partitions on the phone. This means you can flash the radio, downgrade firmware, flash boot.img's with in roms without a issue and a few other aspects. As it sets now with just the unlock you can't touch the radio partition. How ever you can update the radio running a newer ruu.

If s-off was had you could flash what ever radio you would like new or old. Same way with the firmware. Flash back to a older ruu you need to do some hackery where s-off it would just flash and go on it's way.

S-off has nothing in common with unlocking the sim slot for gsm carriers. That would be supercid as many call it. You can have s-off and still not have a unlocked sim.

Is s-off required to flash a kernel?
wanting to try 2fast's but I'm new to htc and s-off...

No, s-off isn't needed to flash kernels. Depending on your device you may have to fast boot flash it, but I'll let others with device specific knowledge chime in there.


Basically, s-off turns the securities of the phone off so that things that are not signed by HTC can be flashed through the boot loader.
