I got my new Zoomit SD card reader for the iPhone in the mail yesterday, and opening the package opened a world of possibilities, making it possible to move full-resolution photos online without a laptop, Wifi, or anything else.

It calls for a little set-up: It needed a charge first, from an included USB charger, and when I plugged the charged device into the bottom of my iPhone4, it prompted me to download the free Zoomit app. (There is also a $2.99 Zoomit music app in the store, but I don’t need it and so I didn’t buy it. I’m all about the photos.)

Next, I plugged into the other end of the device with an SD card that had been in my Canon 990 pocket camera, which contained a few pre-dawn photos, like the one above, which I had taken on my way into New York a few days ago. (No, I was not in the driver’s seat. Distracted driving kills.)

After selecting an image on the iPhone screen, Zoomit sharing options include emailing the photo or posting to your existing Facebook or Flickr accounts, for which you will be prompted to log in.

From Flickr, I emailed this photo to my Posterous blog, which then redistributes to several more platforms, including whichever one you are viewing now.

It’s hard to swallow the $60 price tag at a time when USB SD readers cost so little, but when combined with iPhone apps and social sharing platforms, this baby feels like a game-changer, especially now that more professional-quality cameras are coming SD-ready.

I can’t wait to put it to work in the field.
