Marat Fayzullin has released a port of his own Colecovision emulator for Mobile Phones, heres some info from the page:

ColEm will run ColecoVision cartridge files with .cv, .cv.gz, .rom, and .rom.gz extensions. Place your files into E:\Others\ColEm and don't forget to put COLEM.ROM (ColecoVision BIOS) there.
