Yes, I never said anything about not paying for an app. Maybe that's how you guys roll. I've had my Visa account set up at Cydia/Amazon for ages.
MyWi was updated once the whole time I had it and that was a major update. Weekly or even monthly updates for apps like MyWi aren't necessary unless a new iOS comes along because once it works, it just works. MyWi doesn't have any bugs at least that I know of or affect me in some way so I'm not worried about it. Straight tether to my iPad and I'm good to go.
