You just compared answering a phone to training like a ninja.... heh.Yea your not alone on this one. I still get that problem if I'm in a hurry to answer . But its kinda like training to be a ninja, with the right amount of focus and determination you'll be doing blindfolded in no time. I couldn't imagine going backwards to a blackberry, Droids rule!
I don't understand the problem, but it seems like you may need some use under you belt with it. Hope it works out bud.
