I have an Eye-Fi Pro X2 (old), a Mobi (not quite as old), and a Toshiba FlashAir W-02. The Pro X2 is still my main wifi card - I used it for several years in a K10d and now in the second slot of a K3. I haven't tried the more advanced features regarding the card in the K3. I use it just like in the K10d - it pushes all jpgs to my phone whenever I start the app (provided, of course, that I'm not on my home wifi - if so, I need to drop the home wifi connection on my phone and connect to the Eye-Fi's hotspot). It's easier for me to review the jpgs on the larger phone screen and then delete the ones I don't want. I like that, if out somewhere and not connected to a wifi network, I can start the app and leave my phone in my pocket while shooting. When I'm done, the jpgs are already on my phone or at least in the process of being copied. Works great for high school football games and marching band pics! My wife gets immediate editorial control.
However, the FlashAir seems like it would do what you want. When using it and it's respective app, I get the thumbnails loaded to my phone. I can then select individual jgps or there is a "select all" checkbox to get all of them transferred in one shot.
