Switching from droid incredible to iphone 4s?

I bought alot of apps from the marketplace on android would I be able to get them on the iphone and another question, would the sd card that was in my android fit in the iphone?

Added (1). I'm sorry, "Play Store" is what its called.

I do not believe they would be able to be moved from Android to IPhone technology. I would highly suggest not gettin an apple phone. I've heard of so many problems with them. Android is, in my opinion, better technology.

No, you can't move them over. You would have to buy them all over again.
iPhone's don't accept memory cards either. You're stuck with however much comes installed.

I prefer Windows Phone 8, but if I were you I'd stick to Android. You can keep all your apps, there are tons of Android phones that have expandable memory, and the latest Android 4.1 OS is a lot better than 2.3 (which your Droid Incredible probably has) and iOS.
