Recommend share tracking/organiser software?

[Guest tski]

Hi,

I'm looking for some software to run on PocketPC to organise my shares. I have a portfolio of 5 shares currently. Things I want to do (that I can think of are)..

track their past performance

get share price info. automatically from GPRS

aid buy/sell/hold decisions

calculate profit/loss

.. and any other useful things

I would like to trade a lot more in the future and make more money.

I will be trading exclusively on the London StockExchange in UK £ sterling

I would like to pay as little as possible

I hope to upgrade to a new 3G PocketPC phone running winMobile5.0 in July '06

Thanks a lot for any help you can give. :)
