Infuse - Ipad1 - Iphone5

Hi I have infuse 1.x installed on my Ipad 1 and Infuse 2 on my Iphone 5.
If I buy the pro version on the Ipad, will I be able to use the pro version on the iphone5 too without paying again?
Also will I get video streaming from my WD Mybooklive on the Ipad?

Thanks for your help.

Yes, the same In-App purchase can be used on up to 10 different devices under one Apple ID.

Just tap the Restore button on the second device to restore the In-App purchase without paying again.
