Not sure if this is in the right spot.

I am currently in the process of trying to build a WCF data service to share data across the internet using jQuery. My motivation behind this is to enable an Android/iPhone app I have designed with Phonegap and HTML5 to be able to access data from a database on the internet using jQuery.

I own the Professional ASP.NET 4.0 Wrox book and have poured over the WCF chapter, however have been unsuccessful in being able to implement a cross domain jQuery call of my own despite trying every day for about two weeks now.

Researching the internet leads me to believe I need to use JSONP.

The closest I have been able to achieve is using the code project found at http://www.codeproject.com/KB/webser...JQueryWCF.aspx. Here I was able to publish the code onto server A and then use jQuery to call a method from server B, however since the class definitions was in a .dll file and not a .cs file I haven't been able to modify the data source.

The more I read about this technology the more I realise how deep it is. Can anybody suggest either a publication which addresses cross domain WCF or an article which explains it well enough? Have borrowed numerous WCF books but none of them have contained information about cross domain jQuery calls.

Not sure if this affects anything but I'm using VWDE 2010. I've also installed Visual C# Express when I started dealing with .dll files but don't know if I need it.
