This applies to anything if you define your market tightly enough and "payment processing for iPhone applications" is about as tight a definition as you can get.
If you can define things that tightly how is it different to my going into a shop (for the sake of argument let's make it a shop which sells goods the owner makes and therefore can't be bought elsewhere) which only accepts cash and claiming that they're anti-competitive because they don't accept alternate payment mechanisms?
Unless the iPhone obtained a dominant position in the smartphone market choice exists - you can go elsewhere, as can developers and you can buy (and they can sell) apps from other places and pay or bill in other ways.
That's the market working and that's why anti-trust laws are unlikely to apply under the current circumstances - they're designed to ensure competition and smartphones is a market as competitive as pretty much any on the planet right now.
