the program simply wasn't ready for release. I've used SplashID on my Palm for years without incident, and it was the first app I purchased after the 2.slow upgrade.
I've visited SplashData's forums, to no avail. I finally was able to get the program to sync--it was a Bonjour issue, I think I described earlier in this thread. Had to do with changing a network properties setting that finally did the trick for me.
So now, after a fresh install of the program on my iPhone, I can sync, once. Then the program fails to load on the iPhone. Frustrating.
