changing price and pricing schedule in iOS in-app purchase subscriptions
I can't find any clear documentation on how pricing schedule works with iOS in-app purchase subscriptions. 

Lets assume following schedule of monthly subscription:

    "Existing Date" to "None" - Tier 5 (3.99 EUR)
    01 Aug to 30 Aug - Tier 4 (2.99 EUR)

What exactly happens when some user subscribes between 01 Aug / 30 Aug? 

I understand that he will be charged 2.99 EUR monthly as long as he cancels the subscription. Is that correct? Or, he'll be charged 2.99 EUR for the first month and then 3.99 EUR for following months until he cancels this subscription?

Also: what happens with current subscribers if I change the default subscription price (existing -> none period)? Would they be charged new price for next periods or the price from the moment of subscribing is prevailing until they cancel?
