I really dont want to beat a dead horse, but it's been more than 9 months since i started using IB and i still could not get mobiletrader to work AT ALL. Everytime i try to log in, it says the session has already expired and kicks me out. I did all the cookie/port change/calling support etc..without any luck. All the other websites works without any problems on my phone including mobile trading platforms from other brokers. I am using at&t 3G brandband with tilt smartphone running windows mobile and opera mobile/IE browser. If ANYONE has gotten IB MobileTrading to work consistently on their cellphone please reply with your cell phone model #, wireless provider, and browser used. At this point i am willing to cancel the 2 year plan and buy a new phone / service if it would make mobile trader work.
