Will all notifications in for the notification center work with pebble? For example, I have an eBay app that sends my iPhone a notification when an item is about to end. Will this automatically pop up on the pebble? Also will the default mail application work with pebble, or will I have to use some special app?
Only the notifications listed on the Kickstarter page will be supported by Pebble by default. Other developers can add different notifications using the SDK.
