I have the captivate and the iPhone 4. Since I can't find a way that works correctly to tether my 3G from captivate as a hot stop, I'm using my iPhone with mywi which makes my iPhone a wifi hot spot. I'm able to connect iPods computers and other devices to the iPhone 4 hotspot. But the captivate cannot find the wifi network I create It's WEP with a 10 digit password. Does anyone know why it cannot find the network or how I can get it to work? Thanks!
