I know that everyone wants a free app but you sometimes get what you pay for. Try Beery Buzz and SmartAlerts to really customize LED and specific alerts such as sms, email and callers as well as reminders. The disco option is very unique and has garnered a great deal of attention from BB users and non-users. In the emails, you should also get the license code to register the app. I believe that these apps have a free trial so give them a try.
