MyWi is iPhone application which creates wi-fi hotspot on iPhone and enables tethering through 3G network.

I had already been aware of this app when Cydia alternate app directory "Rock" was released, but it didn't work well on my iPhone at that time.

I tried it once again, and now it works so fine. As its developer said, it seems work faster than PdaNet because of using native routing process, and it uses less battery resouce than PdaNet.
It supports also USB and Bluetooth connection.

MyWi is so nice app that it's worth jailbreaking.

I think WEP should be upgraded to WPA2.
