This idea is for people to help keep in touch with their friends in the game. Sometimes you'll be on the go, and to keep in touch with others could be done through your phone. I reccomend a phone app that allows you to log into any game that you have access to. Instead of playing as your character, you could just have the text screen and a background of the game. Not only that but how about being able to have access to your bag and mail, so you can buy items from world calls and others. But most importantly, you can talk with your guild, friends and even your couple.
