I used it with a Treo from a few years back...entered and exited trades...wouldn't recommend but it worked in a pinch.
More recently, I've used it with my iPhone. It works ok but very barebones. Just account balance, existing orders and executions. If I remember correctly, it can be quite involved (like 2-3 pages) just to select the futures, expiration and exchange.
