I just created a list of mobile apps that help you to find the nearest hotspots. This covers Apple and Android (sorry Windows users). I found many of these mobile broadband apps at www.mobileinformers.com and sorta filled it out with some other great ones I found elsewhere.
I really don't find Google very helpful when I'm looking for a new ISP. It keeps listing ones that aren't even in my zip code. I did find some good sites (on Bing of all places) that let me search for just Internet service providers in MY area instead of the same old ones that don't provide service to my address.
