Thanks for the help.
The updatewait method works very well, for both the jailbreak and usbNetwork hack. I just threw the update on, unplugged it and waited probably around ten minutes. I happened to see it updating both times, and it went through without errors.
Probably the best method to update with a broken screen, I must have been restarting instead of updating.
