Everything Everywhere, had up until now offered one of the better monthly allowance deals with a 3GB data consumption limit on Android phones. It still is, in fact, since its new changes aren't coming into effect until February 1st, but come that fateful Tuesday, T-Mo's understanding of "fair use" will shrink down to 500MB each month -- after which point you'll still get to browse the web and email for free, but any video content will presumably be subject to an extra charge. It's not clear how "that stuff" will be handled by T-Mobile once you cross the frugal new threshold, nor is it clear whether customers who signed up for big bodacious 3GB of data will be set free once this new lockdown on mobile video is in effect. Godspeed to you all.

Update: T-Mobile has responded with a clarifying statement we've added after the break. There will be no surcharges for use over 500MB per month, but once you cross that line, any downloading activity will be "restricted." By which the company seems to mean "restricted to whatever WiFi connection you can scrounge up," because its 3G airwaves will be off-limits.
