BlackBerry 10 allows you to change the name for a text message conversation to whatever you want - so instead of seeing the contact name as it appears in your contact list, you can make it something unique.
For my wife, rather than showing her full name I can simply change the name of the chat to be anything I want.
You can easily do this for any SMS chats you have started, keep reading to find out how.
The custom name you chose will now appear for the chat instead of the contact name or number. Awesome!
