why would people pay for mywi? the iOS thetering app is really great...
If you are referring to the iTether app that was in the app store for like a nanosecond then you should know it is unavailable. Moreover it needs an app on the mac or PC to work--it is not a mobile hotspot like MyWi.
As for me I DID get Tether while it was available. It's great that I can use that with my mb air when I have no wifi.
But for my wifi iPad it is useless--and part of the reason I got a wifi only iPad was because of MyWi.
If you were referring to the tethering built into iOS--which is not really a stand-alone app--then that usually incurs a higher fee. In the case of AT&T that is $45 per month. Considering I never use more than 2GB, even with occasional light tethering, I don't feel it is worth it. I pay for just 2GB, and it suits me fine.
