So basically this is an idea that i know would be difficult to create but still epic. So basically you would have a client side GUI the shape of an iphone or a phone, with this there would be "add number, call, save number and set number" options. Players would be able to set their phone number, eg. 0403358756 or something and save it, people would then be able to search in their friends numbers and be able to save it to a "contacts" list (this is all on the one screen GUI to stop it being complicated.) You would also be able to select multiple friends and hit "call" then the friends and you would enter a separate team chat. (NOTE: this would only work with people on the same server!)
I know im asking for a lot but you must admit it would be cool :P
