Reminds me of when I write a j2me app for matrix diagonalization because we could use the old feature phones as calculators. Nobody thought we'd be mad enough to use those to cheat...
Do you still have the source code for the j2me app?
I hadn’t yet learned to program back when I was still using a feature phone, but I have a lot of fond memories of J2ME applications that I installed on my phones. Mostly games, of course.
I encourage anyone that wrote J2ME games and utilities, no matter how small or big, to upload the source to GitHub :)
