I just activated tethering on my iPhone 4. Whenever I plug it into my mac, the blue bar says that it is tethered, even when my mac is connected to WiFi. In network preferences the USB connection is below the WiFi connection, but just to be sure, can anyone confirm that my phone's data is not being used?
Got a tip for us?

USB Tethering Using Data?

I just did a test. It looks like the iPhone's data is in fact not being used.
As you can see, the url takes the same path when WiFi is connected whether my iPhone is connected or not (through integra.net, my ISP).
When I turn off WiFi, it routes through att.net.

Agreed.
Why dont you turn off tethering then and just turn it back on when you actually need to tether?
Not when you need to charge the phone cause you're just wasting battery and CPU usage having it run in the back for nothing.
I haven't noticed a draw on battery when it is not being used, and it doesn't get used unless there is no WiFi available.
If I wanted to manually set every setting every time I wanted to do anything, I would be a PC user, not a Mac user. I was quit impressed when I activated tethering. It is almost like having a 3G connection directly in my laptop.

It does use battery and CPU cause you obviously see the flashing blue bar.
But up to you, usually people turn off things when they dont use them. I guess Mac users like to leave their lights on when away from home and car running when parked according to your logic
The pulsing blue tethering bar will consume 10-15% more battery according to Inteliborn, the MyWi developer.
Note: For increased battery performance the flashing tethering bar will only be displayed on springboard.
So it does use battery when connected and blinks, it doesnt use any battery when its not connected to a computer obviously.

I know, but like I said above the pulsing blue bar uses more battery.
That's why the MyWi dev took off that stock feature so your tethering and battery will last longer.
That's all.
Do what makes you happy though
Just letting ya know the added feature behind turning it off when not using it. Battery life
