As reported around the web over the weekend, Nokia Messaging for S60 5th Edition has now received full HTML support. As usual, you’ll need to go to email.nokia.com in Web on your phone (a 2MB download). Version 10.1.0.13 will automatically replace your previous installation and will also keep all email accounts and emails. You may remember the issues I've had with Nokia Messaging - at the very least take the usual backups, syncs and precautions before installation.
