Open Thread: How would you improve the iPhone

One of our readers who is a happy iPhone customer emailed us and asked us this question:

iPhone 2.0 – what will Apple add or change about the iPhone to enhance the next version?

Since I don’t have one, I am not sure how to answer this question, and am opening it to all of you. Better way to manage/switch batteries, More memory, More Safari features (plug-in support), Higher resolution camera, Games, GPS, Skype/iChat…Your suggestions please…
