iOS iPhone interface confusions

[Dev2009]

Hi,

I am newbie to iPhone Programming (but I had enough experience with C/C++). I am trying my hands to start with, but I have some confusions regarding iPhone SDK classes.

> How to go for implementing menu (selection wheel)?
> How to communicate with Web Service? Does iPhone works with specific kind-of web service?
> What is the interface to implement Graphs?

Thanks in advance.
