Maybe as of today it does.
You see, back then Keyboard Locker was also free.
But then came BlackBerry OS 5.0 and broke compatibility with earlier OS versions rendering the application useless.
There was no simple fix to it, we had to re-write it from scratch and we did.
It's easy to believe someone else did it later on as well. If they have decided to give it away for free that is their choice.
I had to pay to developers to do what they did and hence I started asking money for it
Later OS revisions also required changes, by the way.
And whoever's offerring it for free won't keep it that way for long...we've been in the business long enough to know it.
