Warning: this is a shameless self-plug, and has nothing to do with Alaska, Politics, The world, whatever.
It’s too boring and too long of a story to tell, but I needed a solid trip bookkeeping application for tax purposes on my BlackBerry, offline. And I needed to get really REALLY proficient in coding this enterprise grade smartphone (which is the main reason I was in the hide mostly for a while). After a steep learning curve I present to you “Trip” for the BlackBerry, which I truly believe to be both robust enough to trust your data to, as wel as having a few smart goodies for making entering trips really easy. Fast trip entry through rolling the distance and having your last 10 destinations selectable. And of course it has persistent storage etc etc. If you want to have it, post a comment with your email address and I will send it to you.
