Long story short, my kid lost an iPod Touch outside at my in-laws' house. I have a portable router that I have set up with my home network's wireless credentials (which the iPod knows), and I can use my iPhone connected to the "home" network and see that the iPod connects to the network when I'm in the yard. But, I can't get the "Find My iPhone" function to work because I cannot connect the portable router to a wired Internet connection. If I try to sign into "Find My iPhone" from my iPhone, it won't login because it's trying to use the unconnected wireless network instead of 3G. Anybody have any idea how I could make this work? It's supposed to rain soon.
