(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.)
I'm sure that's correct in the US, but Europe is still years ahead. It still varies from network to network (and you usually need to look at each separately) but anyone can publish a game, assuming the game is good. Bit of a business mistake on the behalf of the mainstream games publishers - a lot of people have been making a lot of money while they've been sleeping
