We have 5 RSS Feed on some websites. Mobile application will get these rss feeds and show them to mobile users. Application shall sync data when application is opened or it may be scheduled in user choice. Additionally users can add their own 5 RSS feeds.
At the bottom a small banner or text shall be shown. These banners or texts shall be downloaded from our website as txt or xml. We want to put for example 10 banners/text to web site and application shall select one of them randomly.
Application(s) must be run at least on Android, Blackberry and iPhone. If you can make them work on Windows Mobile and/or J2ME it will be better.
I don't know all mobile OS supports widgets or not. I know only Android and Nokia Symbian widgets are available. If possible we want widgets also.
Source code must be published on code.google.com. Future development will be made with developer but we have to open source code because of security aware mobil users.
