Not only is the arena of mobile internet incredibly complex, but it's also constantly changing - sometimes on a daily basis. Staying on top of all of that is a full-time job, and that's exactly what our friends Chris & Cherie over at the Mobile Internet Resource Center do!
If you haven't already checked out their website then I highly encourage you to do so. They provide a huge amount of content for free - industry news, guides and reviews - but becoming a member of their MIA (Mobile Internet Aficionados) group could be money well spent if you want to find the best setup for your specific needs.
