UPDATE: I misread the email from the developer. The Craigslist app will sadly not be free and will cost $5 when it is released. Sorry for the mix up.
The developers of Movela Netflix Queue Manager, Pyxis Mobile, have created a Craigslist mobile application for free for $5. The app is still waiting for RIM’s approval in App World but that should be coming soon at this link. The app will be a full Craigslist client allowing you to browse and search craigslist postings, bookmark and reply to posts, save searches and more. The application supports all categories and all countries supported by the www.craigslist.org website.
You can check a demo of the app at this link on YouTube:
