Eva Mendes is turning into quite the tech-aware star; not only did she shill the importance of recycling cell phones with Scarlett Johansson [1], she is also aware of California's Hands-Free Law [2], wearing her headset with a microphone before she even gets in the car. Snaps, Eva!
Her headset doesn't look like anything fancy — methinks it's a standard BlackBerry one [3] that came with her Pearl. Very no-nonsense.
Looks like she sees benefits besides safety, too — with her hands not holding her phone to her ear, she can lug around magazines with her face on them!
