You mean J2ME, yes?
Let me give you a brief intro.
(1) J2ME distribution is absolutely controlled by the networking providers (the cell phone companies.) So you need to make a deal with one or more of them.
(2) The US cell phone companies today by and large want to limit their engagement to large publishers/destributors. So if youwant to get into the US market, you need one of them to pick up your game in order to get it in front of the cell phone companies.
(I’m not sure where Europe and japan are but wouldnt be surpised if its similar.)
Some folks you might want to try: THQ, Sorrent. There are probably some others other people wil lchiem in with.
