Questions: Finished BG 1..

But BG2 isn't available for iphone yet, and I would like to continue on.

If I get it on my computer is there a way to import my party from my phone?

If I buy it for my mac (and BG 2 come out for iphones), can I then download it on my phone for free too? Or would this considered a separate purchase?

I would prefer to play on my phone because I play in class. Thanks
