Turn off iPhone WiFi Automatically Turns off MyWi

[PIX]

Does the iPhone need to have WiFi enabled for MyWi to function? Normally my phone settings are 3G on/WiFi off. I never noticed this prior to a recent MyWi update that when I turn WiFi tethering on in MyWi the phone's WiFi is turned ON automatically. Conversely when I disable the WiFi this causes MyWi to turn off tethering. Is this normal

I know that MyWi turns on wifi if it's off (kind of has to, doesn't it?) ... but I didn't know that turning off wifi would turn MyWi off too. Although it makes sense. This is good, though - it means I can use SBSettings to kill MyWi (since the MyWi people are either too lazy or too incompetent to make a toggle of their own). Thanks for the heads up!
