Question : Which cell phone is good for stock trading?
I have an TD Ameritrade account and I want to buy a new cell phone. Does anyone know which cell phone in the market is good for trading stocks? Webmail and possibly Level II quotes would be good too. If there are any day traders out there, please recommend a cell phone company and the model you use. Also, do you use any special quote service for level II? I would appreciate you pros and cons of the phone you are using. Thanks!
