Whether you simply need a powerful replacement for SMS interface for writing text messages, a tool for editing your messages, EasyEdit is the right freeware software for your S60. 

EasyEdit is a friendly text-editor for every S60 platform developed in Python with a lot of features.

EasyEdit current features:

• File browser for opening/saving and more.
• Maintains a list of recently opened/saved files.
• Cut/Copy/Paste.
• Change screen size and font.
• Settings are restored when the program is reopened.
• Set encoding of files read from/written to disk.
• Search within a file.  
• Including search for a string forwards/backwards and finding a given line in a file.

Features to come:

• Find and replace.
• Cut/Copy using "ABC" button text selection. This is already implemented by the operating system as well as the clipboard functionality included in the "Edit" menu.
• (?) Line-numbers displayed in status bar
  Since it's quite difficult to obtain keypresses from a text() object, I think this will have to be implemented in a separate thread that updates the staus/title bar... appuifw cannot be accessed from a separate thread! 
• A proper "help".
  (Make "pickle" module work on Python S60 and use it to replace my dictionary parser. )
  I've ironed out bugs in the dictionary parser, and I think it's quite suitable for its purpose. 

You must have python installed to use this application.
