Spread Betting on an iPhone or Android?

iPhone spread betting http://www.financial-spread-betting.com/iPhone-blackberry.html I am starting to spread bet using my iPhone. What should I be careful of? Chris Purdy, Sales Trader at Spreadex comments. Well, there are two things to be careful of when you are trading on your smartphone. The first thing to be careful of is 'fat fingering' - entering a 100 when you meant to hit 10 or sliding your finger across the screen and hitting buy when you wanted to hit sell.
