Well that all depends on what phone you have. Is it WinMo, Symbian, Palm, BB or just a plain jane dumb phone?

scotttrade.com i think thats the website offers stock quotes real time on the iphone for sure but it takes a little
tweaking to make it work on the other PDA phones

why not just use the media net option on your phone and set your stock quotes up on there so u have one click access to them ?

I use Pocket Express by Handmark for my ATT pda for my stocks. I also like the fact that it's one application to check my financial news/stock quotes and also access to all AP news and weather. Plus it's free.

Pocket Express works well. It has a wide range of free content and services--plus more you have to pay for. I haven't actually purchased anything, but in the meantime, there is good depth and breadth of content. It has pretty good stock price info and you can personalize it with the securities you happen to be interested in, but you can't really manage your portfolio. I have a windows Mobile ATT smartphone. FYI, you can get there at http://tinyurl.com/attexpress.

Another thing that Pocket Express offers is a link to all the hot stocks of the day. I usually check that link in the morning to track a few of those stocks for my day trading...
