No, the jailbreak package isn't really signed
. [The K3 one isn't signed at all, and the one for FW 2.x is half-signed, using an untouched bundle file & install script from a minor official update].
The custom packages are signed, with the key provided in the python packer.
And thanks
. I think I might approach the critical point where there's more comment than actual 'code', but still
.
