OK, I have ZERO experience with the handset makers like Nokia/Qualcomm, but I don't understand what that has to do with anything. When you buy a game for your phone it comes from the carrier like T-Mobile or Sprint, not Nokia. I'd be hard pressed to believe that when T-Mobile sells Bejewled for $6 the developer is getting anywhere close to 70% of that money. T-Mobile isn't a magic company. Their overhead figures have to be close to the 30% figure too. Given that they state substantial profit comes from selling games and ringtones, that makes me expect the cut to the application developer is much less than 70% for T-Mobile to make any money.
But I haven't dealt with T-Mobile or Sprint, so I don't know. If you have let us know because that would be valuable experience to share!!
I don't have any experience either.
But how much the platform pays to the developers is directly proportional to the number of quality and quantity of apps and games available to the platform.
There are a lot of premium priced games on the Get It Now --- $12 for a mobile phone game.
