Eye-Fi Direct Mode
Eye-Fi's wireless SD cards have always been a great way to beam photos directly from your camera to your computer as well as services like Picasa and Flickr. But until now, they've required a Wi-Fi connection, which limits their use in the field. Not anymore: Later this year, Eye-Fi will release a free firmware update for its X2 cards that will create an ad-hoc network and beam photos to an iPhone or Android phone via a free app. What does that mean? It means you're no longer limited to your smartphone's camera when quickly uploading pictures to Facebook, Twitter, emailing them to friends, or whatever else you like to do with them. Now you can whip out your DSLR or high-end point and shoot, take the amazing pictures those cameras are capable of taking, and beam them to your smartphone instantly.
