Well my main problem is the details page of the product! So if you know a nice tutorial about the details page that will complete the appStore application I want to do :)

ah ok. ive edited my post. and you can now check out the video an di believe thats what you want. check the first 5 seconds of the video and you will see what i mean notice how the image gets locked once in focus until the user goes to the next image which is again locked once in focus. The tutorial will show you how to achieve this. Start from fresh.
Pavan
OK we are actually there! But again how will I make the detail page. I mean how will I combine the textview with the uiscollview this is what I really want. :)
auslander
you have a UIView, with a text view and the uiscroll view on there.
