Unlimited data means UNLIMITED DATA..... Doesn't mean it has to be fast. Stop trying to twist the meaning of it and read it for what it actual says.
You are so patently wrong it's hardly worth debating you. It's like explaining a complex mathematical formula to someone who doesn't even know what a number is.
A limit is a limit is a limit.
Those of us who signed up when 3G first became available signed up for "Unlimited 3G." 3G is a common term utilized in the cell-phone industry, and although a specific speed isn't often mentioned, AT&T has put ample promotional effort into communicating that their 3G is the "fastest." At the very least, 3G is promoted as something capable of loading a web page in a reasonably quick fashion.
Even those who were not sold "Unlimited 3G" but rather "Unlimited data" have a colorable argument. Constraining the speed of data after an arbitrary number of Gigabytes has been reached is a limit. Why? Because: (a) the phones are being throttled to the point that, for all intents and purposes, they are unusable on AT&T's data network; (b) creating this arbitrary "5%" number is, by definition, a "limit," as in "you are limited to the bottom 95% of data usage, after which we throttle your speeds"; and (c) the whole situation wreaks of bad-faith business practices and "technicalities" which neither consumers nor courts typically find appealing.
