Would this work on the Sony Ericsson T630?
A few sources say that that phone supports mobile JAVA apps(J2ME).. not sure which midp version of this game you should download, though. Why not try it out?
EDIT: After a further look(i.e. following the link on the game's website), it seems like MIDP-1.0 is supported by your phone. But if it's like my N-GAGE QD(also MIDP-1.0), you can still use the MIDP-2 version, if you turn off either the sound fx or music.. as one will cut the other out (once again, I don't know 100%.. try both versions with all sounds, etc.. try until it works
).
