Hi, help on this would make you my hero!... and Role Model!

Can you import hands from pokerstars to hm2 that you played with hm2 closed? Even days later?
If so how do you do that?

Also can you import hands you played on an iphone?
If so is there a limit to how far back you can go or how many hands?
If its possible, how do you do it?

Thank you!... Ever so kindly!... .. .
Please and Thank you, Make... My... Day.
