I am not sure how many of you are trading from your BlackBerry but Tashanna let me know that the popular iPhone application, iStockManager, is now available for BlackBerry users. Their app essentially gives you access to your TD AMERITRADE account where you can check the market and place trades (equity & options trading).
It also gives you access to streaming data, real time balances and positions, news and more. I am not sure why anybody would choose this over the other free MarketSimplified AMERITRADE application but I guess it is good to have options. I have never used either of them so let me know if you have.
Check out iStockManager for the 8900 Curve, Storm, & Bold at istockmanager.com/blackberry/
