SMS app with kalender function
 

Does anybody know if there is any existing SMS app for the N900 that can send delayed sms messages. Meaning if I send a sms i the middle of the night i may not want the reciever to have it before nine o clock in the morning.....Or mayby I want to program all my friend birthdays in the kalender and for the phone to send a gratulation message the same day.

Or should I buy a Iphone.... :D
