I test-drove the Eye-Fi Mobile on my iPhone 4. With the exception of slow wi-fi when trying it out, all went very well. I'd be interested in hearing from others who have used Eye-Fi Mobile and if they had any challenges of which they may need help and/or suggestions.
With Eye-Fi mobile I especially enjoy having the opportunity to view and manage my photos when not nearby my computer. With four cameras, two iPhones (4 & 3Gs), one iPod Touch and an iPad set up as devices, this "old" mind can't always keep track of what's been uploaded and what's not been uploaded. Eye-Fi Mobile helps out with those challenges.
Thanks for including Eye-Fi Mobile as part of the suite of software Eye-Fi provides to make lives easier, quicker, and user friendly.
