Difference between these two tethering icos
First (white icon) is minimus ROM and second is CM 10.2 nightly, but I've used a couple other roms and the icon changes between them too.
I notice that any rom with the tethering icon in the first pic causes really annoying stutters if you're gaming on that connection. Complete timeouts for 1-2 seconds at a time.
Any rom with the second icon is fine with all games.
