Best Phone for Trading

Hi I am due for a Free Upgrade soon (October), I actually spoke to my broker today, and I was looking at the Samsung Galaxy. He said this is the phone he has got and it works perfectly on there platform (IG Index).

I don't want to go the I-Phone root, so will probably go for the Android type, but I don't want a massive phone, and a phone that I an actually use for phone calls.

i think the iphone is currently number 1 because every respectable broker has an iphone app. Of course a tablet would be much better, but we're talking about phones.
