iOS Question

How much RAM is there in an an iOS (Iphone/iPad/iPod Touch) Device?

Different iPhones have different published memory 4GB, 8GB and 16GB. The touch can have 32GB. My understanding is this is the off-line memory (disk alike).

How much actual fast ram is there in the device available for my Cocoa Application?

Is there a preconfigured virtual amount?
