which made me think I would need to figure out how SSH works again. I haven't used it since college, and I remember... nothing. Is usbnetworking still needed for this? Once I actually unpacked the developer certificates zip and read the read me and found out it was packaged as just an update .bin file, things got a lot simpler. I have usbnetworking installed now, and everything is working, and I was probably better off reading all the extra stuff anyways, I'm just curious if things had changed during development to make it no longer necessary?
