Maybe one that will list tasks by categories (just like the simple Palm OS To-Do) without using "filter" function to do this...and this program should integrate with the BB's Task app so that we don't have to re-input all the tasks in this new app.
I'm demo'ing it now. It's nice. I'm not sure that it solves the calendaring problem - things like linking contacts/memos/tasks/appts. together. If you've ever used a pocket pc, I'm thinking something like PocketInformant (the PIM app against which all others should be judged).
Corporate App - J2ME Midlet for Wireless Global Address List Synchronisation
Don't even begin to ask how we ended up doing this but we have been synchronising a cut down version of our Global Address List with the handheld using Public Folders and Desktop Manager. The problem we have is that BES 4 won't wirelessly synchronise with a Public Folder, therefore, an application to do to this would be useful.
helo! glad to hear you are willing to develop apps for BB! I think a killer app, highly sought after would be to allow installing applications on a BB from a MAC and somethign that will let Mac users tether their BBs as a Modem. I dont think either should be too difficult, since its already possible on Windows...???? and the BB runs on JAVA (please correct me if i am wrong) and Java is supposed to be platform independent...???????
there are other apps which I can think of but are more niche. Mostly rooted in teh film industry. Let me knwo if you are interested in developing such stuff...
