Blackberry app based on iphone & android versions

We've an iPhone (Objective C) and Android (java) app already and we need an BlackBerry version of it. The BlackBerry version must have the same features as possible. It's has to be overall similar in graphic design, but we are open to suggestions of improvements according to blackberry interface capabilities. You must see the application's screens and functionalities on the hotsites: [login to view URL] and http://android.ricardo-vargas.com. (please, see the screenshots and all the description there as well) We can share the source code of both versions to help you, after bids are closed. ABOUT THE APP It's an app that retrieves the content from our website ([login to view URL]) which runs on Wordpress. There is also a plugin on Wordpress that retrieve the content from database and send it to the iphone app using Json. It has a bilingual interface/content: English and Brazilian Portuguese. (We can help with the translation as need). Main Features: 1 - User can browse a list of podcasts from our site's feed (both languages), select a podcast and listen to it. Mark it favorite to future use (in a favorites list). THIS, the podcast section of the app, IS THE MOST EXPECTED FEATURE. 1.1 - The podcast is downloaded in the background to the phone memory so the user can listen to it while in offline mode. This is, I think, the most difficult task to develop. 2 - User can browse our youtube lists (there is an english and a portuguese video selection on youtube list) and play the video clicked. 3 - User can read other sections of the main site ([login to view URL]). Please, refer to the screenshots oh both hotsites: [login to view URL] and http://android.ricardo-vargas.com. ABOUT THE PROJECT We are planning 5 milestones: Milestone 1/5 - Podcast section done Milestone 2/5 - Video section done Milestone 3/5 - Twitter feed Milestone 4/5 - Other sections (html based ones) Milestone 5/5 - Final version with full functionalities Feel free to ask any questions! Cheers from Brazil!
