Hi, I'm currently in design of my first mobile aplication that has to run in 3 diferent plataforms (Blackberry, Symbian and Windows Mobile), I've checking my options and I'm inclined to chose Perst Lite, in order to get a better performance working in a OR DBMS and unify the architecture of the aplication, but there are some past aplications that are suposed to keep using SQLite (windows mobile ones) and one of my bosses wants to keep that intact....
