Until now, using an Eye-Fi SD card to share photos and video from a camera on the Web was impossible without a Wi-Fi network. With the new X2-series cards, users can upload and e-mail shots anywhere there’s cell service. The cards establish a secure, wireless device-to-device connection between any digital camera and a supported Android or iOS handset. Photographers use a dedicated app to access the photos on the card and download them to their phone to upload to Facebook or share over e-mail. Cards from $80
