Is there a way to customize the iphone keyboard? Say I want the number pad with a comma button and a period button added to it.
A:
Yes, as of iOS 3.2. See this answer. You may not be able to edit the default keyboard, but it's not difficult to reproduce with your own view.

A:
What you are looking for is a custom IME (Input Method) which is not directly supported in iOS (true custom IMEs have been developed, but require jailbreak). You can create a custom view, but just for your application.
