Romeo seems to work fine with the new Sony Ericsson T637 (the US version of the T630), even though it isn't on the supported phones list. As nearly as I can tell, Romeo is roughly the equivalent of Salling Clicker, but for no cost. The interface isn't totally clear, and the documentation doesn't always help, but again at the price, I'm not complaining (and thank the developer for his efforts!). My only concern is that the developer may not be actively updating the application at this point, which if it's true, would be a real shame, as its got a lot of potential.
