Need Broker - MT4 platform

I've pretty much determined that, since I cannot find another trading platform that will work with my PDA, I'm going with MT4. However, I'd LIKE to start with a mini account, although it's not necessary.

So, which brokers are somewhat reputable? It seems that I can not consistently find good information about any single broker out there. I have a demo account with interbankfx, but I'm getting a lot of mixed signals about them.

Any suggestions?

Question: Why do you use them? Are they not just an affiliate of mbt?
Also, does mt4 really work with mbt?

I don't see where their trading platform works with a PDA (using Windows Mobile 5).

how about northfinance.com ?
I had been trading with them almost 1 year and can use MT mobile.
