iPhone openID authentication and embed HTML

Question

Question 1

I want to make IPhone application that uses OpenID for authentication. I have found janrain described here : http://techcrunch.com/2010/04/05/janrain-openid-iphone-apps/ this is exactly what I want! However is commercial licenced is there any open source/free alternatives?

Question 2

I also want to later make Android , Windows Mobile , etc versions of my applicaion. To save making multiple application I thought I can make 80% of my application in HTML the other 20% needs a GPS so would need to be an iPhone app. Is it possible to make an IPhone application that some of its screens are really web pages? I do not want to open Safari I just want to embed HTML directly into an application so the user would still think they are just in the application still?

Answer 1

You might want to check out http://www.janrain.com/blogs/janrain-engage-iphone for OpenID on the iPhone

Answer 2

I found I can use a HTML/CSS/Javascript solution to develop my App.

And still have access to the GPS etc.

Using http://www.phonegap.com/ and http://jqtouch.com/ etc

This should mean I can use regular OpenID or yahoos mobile phone optimised version here http://developer.yahoo.com/blogs/ydn/posts/2009/10/yahoo_openid_an/ so I can keep my solution 100% web based.
