Do the most common (widely used) brokers supports trading with MT4 Mobile SE?

Hello

I’ve heard somewhere that some brokers doesn’t like to allow trading with MT4 Mobile SE. They do however allow using of MT4 Mobile (non-SE).

How is the status on this subject? Is it meaningless to get a smartphone and MT4 Mobile SE, when no broker supports it? Is this something that will change in the future; in which direction is the progress going? Towards or from trading with smartphones?

How about non-MT4 brokers. Like dukascopy and EFX. I’ve heard they support some kind of mobile trading, but do there software work on Windows Mobile smartphones? (E.g. Windows mobile classic edition OS’, not professional which is used in pocket PCs).

How do the mobile traders here work?
