I wrote a blackberry application for Playstation for the 2010 E3 exhibition. All the design was done by Exposure LTD, and I wrote the blackberry java app which displayed information about the exhibition and about Playstation.
The app can be seen here - sceestart.com/bb.php - though you can not download and use it unless you are a member of the press and have the relevant username/pasword.
The application shows a map of the exhibition halls and the ability to show toilets/exits/first aid etc on that map. There are also lists of local venues for eating/drinking/entertaining with the ability to go to their websites, phone them, or view them on a map.
It also has information about the latest playstation games, news, and even a twitter feed - all of which was not stored on the phone but was read from CMS via the internet.
The app is written in Java using blackberry rim's API's where needed. It was written in OS 4.5 and can be viewed on portrait (Pearl) or landscape phones (bold/curve).
This was written under very tight timescales as it needed to be finished for the exhibition in late June and they approached me one month before. It involved working long days (sometimes nights) and weekends as the deadline could not be moved.
