MeBoy is a Gameboy emulator for mobile phones (which means you can use it to play Gameboy games on a mobile phone). It works on phones with support for Java Micro Edition, specifically MIDP 2.0. Your phone manufacturer’s web site can tell you if this includes your phone.

MeBoy supports both Gameboy and Gameboy Color games, and with version 2.0 you can even play your games with sound!

With MeBoy you can also save your progress at any time, whether the game itself supports saving or not. Any number of saved games can be stored concurrenly (only limited by your phone’s available storage space). Since version 2.0, you can share your saved games with your friends via Bluetooth..
