Somebody correct me if I'm wrong...If i have MyTether 1.5 installed and have root access, and just put the following 2 lines in terminal as root, this is going to work just the same as the directions in the OP would work, right?
cd /lib/modules/2.6.24-palm-joplin-3430/kernel/net/wifi/
wget
http://www.mediafire.com/file/jywhtmrymzl/sd8xxx.ko
And then reboot, and I'm set. Any problems with changing the file this way instead of through WebOSQI?
ETA: Nope, this doesn't work right, hadn't looked at the link before.
ETA Again: It kinda does work with a couple more steps. In a browser, navigate to the link above, the one given in the OP, and copy the download link off of that page. Then in putty (or whatever), create a temp/backup folder in the directory given in the OP and wget the file using the download url you just acquired into the temp/backup folder. Then, just use cp to make a back-up of the 1.2.1 version of sd8xxx.ko on the pre, and use cp again to replace it with the sd8xxx.ko you just downloaded. Reboot, and done. Pretty simple, for those that already have root access and don't carry around a USB cable with them like me.
