ok if your on the 209 leak or 181 you go to settings then tethering&mobile hotspot then usb tethering and there you go
I've also noticed (when doing the SQLite hack) that USB entitlement check is by default set to 0. It's been that way for a while. I should know since I'm writing this up on my phone via USB tether (waiting on a USB wifi adapter for my desktop). Actually, the phone is working as a WiFi adapter right now since I've enabled WiFi on the phone and tethered that connection. Hope that helps. For someone like me with Comcast way out in the boonies of Virginia, having the tether option is indispensable as is my *currently* unlimited data. I tend to use about 4-6 gigs a month. Maybe more since my new desktop arrived. I hope this doesn't constitute a gross abuse of unlimited data since I am a heavy user (on the phone itself usually).
