Did it look like that? That is what an app that is waiting to download, or download an update, and install it will look like. That is why after you where on a wifi network it went away, as it was able to download.
I use the eye fi pro in direct mode with mwyi.
FYI: It's one or the other. Either you are using MyWi or Direct Mode. You do not
need MyWi, a Jailbroken device or even any app installed other than ShutterSnitch to upload from an Eye-Fi Card directly to ShutterSnitch without a router. You may want to simplify your setup so it is easier to use and more reliable. Check out the info on Eye-Fi's sight about Direct Mode.
You've got to find what you love.
