It didn't take long for bugs to arise (who would have thunk it :-) ). Here's a summary of what changed:
1) The notification information on the birthday information screen (the dialog that comes up after you click on a birthday) now displays the correct notification date and time.
2) The notification time displayed on the same dialog now displays minutes correctly. It was showing 4:4 for 4:04.
3) The listview for the birthday list actually scrolls now - so if the number of entries in your list exceeds the amount of space it takes to display them, you are able to scroll to see the rest. Minor oversight.
This is it for now. Please continue to report bugs if you come across them!
