Unfortunately Unusable
It was working fairly well for a while, but now that I am up to 15 groups, it crashes -- a lot.
The application also has a facility to manage your contacts. In the list of contacts, it has a line below the name of each contact that identifies the group to which it belongs. Lately, however, I have noticed that this function operates sporadically.
For what its worth, here are some technical details of my device:
Device model: iPod touch
Generation: iPod2,1
OS version: iPhone OS 4.0
