I having quite a bit of trouble with Android (Galaxy S2), Eye-Fi and Xerox Mobile Scanner.
1) First of all, I see release notes for different versions of the Android app. But not for the version I downloaded. I have v1.2.3 says the About box. Can you make release notes available for this version as well?
2) When I am connected via WiFi with the Eye-Fi card, and I go to Settings | Eye-Fi device settings in the app it says "We are having difficulty connecting to the Eye-Fi servers. Please check your network connection to access this functionality.
I have the impression that if I am in situation 2), that the mobile scanner can not transmit it's PDF to the Samsung. On the other hand if I am connected to Eye-Fi Wifi it will be clear the Samsung is trying that connection to access the Eye-Fi servers and not the 3G connection provided via the SIM card (hopefully there is a fallback implemented here?). So I am a bit confused about how this is supposed to work ... and would like to hear some suggestions on what to check for such that I can resolve my problem and scan happily.
