A while ago I wrote about how to do a wifi iPhone tether with a SOCKS proxy. Now, I’ll be writing about a Bluetooth tether on 3.0/3.0.1 with a 3G/3GS. To make this work on 3.1, you will need to enable tethering separately, which can usually be done by installing the “Internet Tethering” package in Cydia. This does NOT rely on that uit.sh script floating around, and will work on any Linux system with bluetooth. I used my Fedora 10 laptop for this.
