In the tutorial, Jeremy covers elements of bbUI.js that he used in Crochet Buddy HD. If you are looking to get started with BlackBerry WebWorks, this resource will definitely get you on your way. You will see everything from the action bar, lists, buttons, and screens with screen shots, sample code, and step-by-step instructions - and when you get to the end he's got all the tutorial source code for you to check out for yourself.
Let's give Jeremy a big thanks for this contribution to the developer community, and head over to OSBB where you can read the full tutorial. And don't forget to show your support by purchasing the Crochet Buddy HD app for only $0.99 via BlackBerry App World!
