There's good news for frequent international travelers and Fon users alike today. Fon and AT&T have entered into a mutually-beneficial agreement to let each other's users access both networks when out and about. So AT&T International WiFi users will have access to Fon's distributed WiFi hotspots without having to buy the Fonera hardware, and Fon users won't have to pay an access fee on the AT&T WiFi hotspots that still charge one.
It could only last so long. Boy Genius Report received a tip today that T-Mobile USA is making preparations to follow other carriers' foot steps and is going to start charging for tethering on November 3rd. The $14.99 monthly plan is a surcharge on top of an obligatory $19.99 Unlimited Web plan, so don't go thinking you can replace one with the other.
T-Mobile was once praised for turning a blind eye to device tethering and portable WiFi hotspot functionality, but times are tough, so what better way to make money than charging customers for the same data twice?
