There's only one way to hold your phone confourtably, and it is with one hand. The good thing about 3.5screens is this, if you no longer can do everything with one hand and need both, it' s better going with the 4.85 of the galaxy s3
I can one hand the 4.7" One X, no problem, and I have very average to maybe smallish hands. The whole "you can only one hand an iPhone sized phone!" is sheer Apple propaganda.
