Sprint’s new T-Mobile-style “unlimited” data plan throttles you after 1GB

Sprint unveiled a $40-per-month "unlimited data" smartphone plan that comes with 1GB of high-speed data. You can use all the data you want, but after that first gigabyte, you'll be throttled to lower, 2G speeds for the rest of the month. The $40-per-month charge also includes unlimited talking and texting. For $50 per month, customers get 2GB of high-speed data and slower speeds thereafter.

This is similar to plans offered by T-Mobile US, which sells "unlimited data" service that throttles customers after they've used up their high-speed allotments. Sprint is undercutting T-Mobile on the price by $10 per month. However, Sprint's throttled speed is apparently lower than T-Mobile's. While Sprint's announcement didn't define "2G speeds," in the context of international roaming, Sprint has defined it as "up to" 64kbps. T-Mobile defines 2G as up to 128kbps. (We've asked Sprint to clarify its 2G speeds and will provide an update if we get one.)
