I never saw that commercial. In general I tend not to watch Apple commercials, not because I am a hater but because I already know everything about their products. Maybe my problem is how I am holding the phone. When using one handed I tend to have the phone wedged into my palm with my pinky and index finger tip on the left side of the phone (to hold it firmly in my palm). In this manner my thumb can not reach all the way over. Similarly, if I hold by the bottom my thumb can't reach the top. If I hold higher up, I can't reach the home or menu key without hitting something on screen. If however I hold the phone less securely, in other words just resting in my palm with my index and pinky finger tips on the bottom of the phone I can reach everything. Unfortunately in that position I am always afraid that the phone will fall out of my hand.
PLEASE if you have a suggestion let me know. I really want to keep this phone!
