might have found a way but had no time to test it properly since im currently overseas and its late here, what u wanna do is go to ur call log, look for a cell phone number u dialed thru skype but that is not saved in ur address book, click it then click text message, it will then open a conversation window with the icon being skype in the text input field, try sending that person a text, lemme know if it works thnx
