I'm sure it wouldn't get past the Apple Censor Board, but that's about the point that I would put in the in-app purchase button (for the item at 130% of my base price) right next to a "Click here for 30% off!" link. All of a sudden, your full retail price is heavily discounted and a lot more attractive!
The guidelines stipulate that the in-app price must be the same or less than your regular offer.
(You could possibly have a separate offer with iOS availability at a price that compensates for Apple's cut, which means you would get Apple's cut from everyone buying iOS availability outside the app.)
Technically, they state you must have the same or better offer. Better isn't the same as cheaper, it can mean more expensive with more features, so an "premium iOS offer with added features" for 30% more could be justified :P
I stand corrected, it's more yucky than I imagined. I can imagine what's going through their minds doing this, but this is just plain stealing.. they want to drive off any one that sells products that can potentially compete with them (kindle vs ibooks?), but damn, again they're killing off everyone with a bazooka, again. It's like the dev license change to kill off flash apps that ended up hitting almost every top app vendor out there.
They might back down from this like they did for the dev license changes, but this habit of always changing the rules in the middle of the game regardless of who gets hit is really getting old.
