Have had a search and think know the answer but (seems to be a general rule that only one sim slot works for data) but have seen mention in posts of newer phones which have 3g on both sim slots ....
I would like to use 2 sims for :-
A) Work Sim
Email (get lots of email and dont want to use my personal data plan)
Work Apps (construction projects data base)
B) Personal Sim
Im guessing this level of control is not yet avaliable ?
