Recently Julian and I demonstrated the use of PhoneJS and a text editor to create a WebApp that was capable of capturing a photo, grabbing your current location and posting the photo and a message on Facebook. You can watch the webinar on our Youtube channel here.
A lot of people have asked for the code, so I am including it here for you to download and play with. Note: You need to download PhoneJS also from http://PhoneJS.DevExpress.com
For more information on the OAuth2 Library see http://code.google.com/p/gwt-oauth2
Don’t forget if you want to experience PhoneJS inside Visual Studio, be sure to check out DevExtreme, the cross-platform, multi-device development framework, optimised for Visual Studio.
