David Beckham was one of the first iPod celebrities and it's a fair bet that the Los Angeles Apple Store rushed an iPhone to his swanky villa, so Proporta's new iPhone screen protector should catch his attention.

The Echo is a washable mirror-screen protector that turns the iPhone into a mirror when the display backlight is off. When turned on the screen is a little duller than usual (which will put off some) but protected from scratches, etc.

It's a neat idea that might appeal to those people who apply make up on the bus, the extremely vain, or nosy parkers who want to catch what's going on behind them. It would also be extremely useful for heliographers.

Observers of youth antics have noted seeing mobile users use their phone's camera to take a picture of their face so that they can then get their hair straight or apply more mascara. With Proporta's Echo there's no need to even turn your phone on for the same effect.

The screen protector is easy to apply, and Proporta has helpfully included a screen cleaning cloth and a plastic applicator. It peels off with no ill effects to the phone, and can also be easily wiped clean.
