BleepingComputer.com: Which smartphone?

Hello all,
I am planning on purchasing a smartphone in order to execute trades on the stockmarket.
I have not used a smartphone before and was wondering if anyone has any ideas, preferences or recommendations for
a particular brand of phone. It doesn't matter whether you trade or not, my primary concern is ease of use.
Thanks in advance,
Peter

I've personally only used Android based smart phones. There fairly easy to learn. It's most the less like a computer. Accept a touch screen. And good thing about Android phone's is the market for Apps. Most of them are free and there's ALOT of different one's. Here's some stock market apps I found in 10 seconds by using Google. http://www.thestreet.com/story/11207254/1/5-free-android-stock-market-apps.html Android phone's also aren't as expensive as say an iPhone. I personally use the LG Optimus V from Virgin Mobile. You can check it out here: http://www.virginmobileusa.com/cell-phones/lg-optimus-v-phone.jsp

pJ,
Thank you for the info, I will take a look at those links.

For ease of use the iPhone is probably the best. However the Android is not far behind. This site is pretty good to help decide: http://wuggee.com/best-smartphones.html
