Usually I find phones promoting films kind of lame, and bling phones too garishly bourgeoisie, but something about this Iron Man phone is thematically spot on.

The 18-Karat Gold Iron Man phone was essentially a LG Shine slider phone, souped up with then exclusive content from the film and the gold and red color scheme of Tony Stark's armor. While the phone cost $2,000 it was never available in stores, and near as I can tell only 10-30 were ever made, given away in various promotional contests.

LG even came up with a killer website for the phone here, but unfortunately even if you wanted to shell out 2K for it, they're not actually selling them.
