I am using a purchased copy of MyWi and ever since updating to 4.12.5, the MyWi USB feature has stopped working. the Wifi feature works, though. I tried rebooting my phone and the program, so I'm curious if others have this problem too?
I just found while searching that in order for the USB to work, you have to have the latest version of iTunes on your computer. I am going to try this out now. I just got a new laptop and this one doesn't have that when my old one did and the USB worked fine... so far, it makes sense.
