4G-ish

"4G" is meaningless. "4G" phones and modems offer less bandwidth than 3G ones, carriers are rebadging 3G gadgets as 4G ones, and even where it's available, speeds are throttled to the kilobit range. PC Mag point out that there is nothing to stop carriers like AT&T lying in their ads: "AT&T's tactic seems to ruin the entire idea of 4G so as to cloud the picture." [PC Mag]
