Thanks Enrique,

Is there any older version that works on 3.1.3 that I can manually install on the iPhone. I had to downgrade my iPhone 3g from 4.2.1 to 3.1.3 due to the performance issues. I cannot go back to 4.x as it becomes unbearably slow. If you can send me a link for the older version of the app, that would be great so that I can use in tandem with my iPad.

btw, apart from bluetooth, is there any way to make the app emulate a wifi hotspot similar to the eye-fi cards?

as a follow up, would this run on iphone 3g running iOS3.1.3 (I have no plans to upgrade to 4.x given the old hardware).
