Does going from a phone with a QWERTY keyboard to an iphone take much getting used to?

My wife's iPhone HAS a QWERTY keyboard.

At first yes, but then it becomes natural after some usage. I have been using Iphones for over 3 years now…

You can always use talk text.

QWERTY refers to the layout of the keys, not the presence of a physical or virtual keyboard. Most phones (including iPhones) have QWERTY keyboards, but I think you're talking about switching from a phone with a physical keyboard (like a Blackberry) to an iPhone (which has a virtual keyboard). As someone who has made that transition myself, I can honestly say that it is very easy. I actually type faster on a virtual keyboard (especially with the help of autocorrect and suggestions) than I do on a physical keyboard on a phone.
