Like others i have an old device with Android, a Samsung i5500 and some years ago i did developed a game for it to teach my daughter the numbers when she was 3 years. The device is still working, it had Froyo Android 2.2 and upgraded to 2.3 Gingerbeard with Cyanogenmod. There seem to be two problems to resolve, future problems and past problems, because it is incredible difficult if one wants to develop something for an old device how hard it is! Like inventing something new. All versions are deleted, unavailable... may be for that reason i have some hobby of collecting old software and backing up. I hope i help somebody with this.
