It works, but in beta 4 there appears to be a bug with the loading spinner displaying at the bottom of the list properly. I’m checking the forums quick to see if anyone else has had this issue and should open a ticket soon.
Otherwise it’s working great with this format:
<ion-content class="has-header">
<ion-list>
<ion-item ng-click="open(post.url)"
class="item"
collection-repeat="post in posts"
collection-item-width="'100%'"
collection-item-height="70"
style="width:100%">
<h2>{{post.title}}</h2>
</ion-item>
</ion-list>
<ion-infinite-scroll
icon="ion-loading-c"
on-infinite="loadMoreData()">
</ion-infinite-scroll>
