Despite the defiant claims of the major smartphone companies that they're not copying each other (despite litigation finding evidence to the contrary), there's little doubt that the market's handsets - by and large - tend to follow the trends of one another. One feature that seems to have unfortunately died out, is the once-popular BlackBerry / Nokia LED notification light. Particularly useful if you find even the vibrating alert to be a tad obtrusive, it allows your device to communicate a notification without any sound whatsoever. While the OEMs appear to be neglecting a feature many of us would like to see return, the commendable work of those over at XDA-Developers has lead to something of a solution in the form of ButtonLED, which turns your hardware button into a makeshift notification light.
