I downloaded this theme and have to admit this is an awesome theme I am noob but learn quickly (I hope so). So I can explain how to translate this theme. Hope Seraphan will not be angry - don't touch the html. This is for the position of the notification. - go to private folder - edit the calendario.js
Now the line > var giorni_sett = new Array('D','L','M','M','G','V','S','D'); Remplace le capital letters by the ones in your language (D is for Sunday, L is for Monday, etc.)
Now the line > var mesi_anno = new Array('Gennaio','Febbraio','Marzo','Aprile','Maggio','Giugno','Luglio','Agosto','Settembre','Ottobre','Novembre','Dicembre'); Remplace the months by your language months (Gennaio is January, Febbraio is for February, etc.).
I didn't find the way to change the clock format Sorry...
I jailbreaked my device few days ago and have difficulties sometimes, no everytimes LOL
