One of what I find to be a really useful applications on my BlackBerry got a nice upgrade not too long ago. Later Dude has now reached a "Pro" level and Fabian has taken all the great feedback given to him on the application and for the most part implemented all of your requests.
Fabian has now made the application accessible on any screen which allows you to add calendar entries for call back reminders incredibly fast as it can now access all the available applications such as SMS, email and even your call log and address books. So at any given time adding an entry to set as a reminder is just a click away. It's a great update to an already awesomely functional application. Be sure to check it out. The cost is $2.95.
