Working for me but had to downgrade
I have MyWi 4.5.1 which worked fine when I was on 4.1. I used greenp0ison to upgrade to 4.2.1 and then installed MyWi. USB and WiFi work flawlessly as well as the onDemand feature. Bluetooth tethering worked once and after I disconnected never connected again. I downgraded back to 4.1 and installed MyWi 4.5.1 and everything is back to normal.
The other thing that is awesome about bluetooth tethering is that I can leave bluetooth enabled and when I need it I can tell my MBA to connect to it. That's one feature WiFi cannot duplicate.
So if you guys can try to downgrade to 4.1 and try MyWi 4.5.1
The developers (intelliborn) website says
Supported iDevices
iPhone 3G/3GS/iPhone 4 iPod Touch 1G, 2G, 3G
iOS versions: 3.1.2, 3.1.3, 4.0, 4.0.1, 4.1, 4.2.1 (partial)
I wonder if the 4.2.1 (partial) is the bluetooth problem
