This feature is better than nothing. But, the most useful feature, a software-based Sleep/Wake mode...I am sure every iPhone users had similar power button
There *is* a software-based substitute for the Sleep/Wake button. Check it out at: Settings> General>Accessibility>AssistiveTouch. It's not that well-known in the U.S. but it's very popular in Asia. I once read that a huge percentage (>50%) of iPhone-owners in Asia use this feature, specifically to avoid over-use of mechanical buttons, which *will* break eventually. Mine did. In the U.S., I think a lot of people replace their phone before the buttons are likely to malfunction. (less)
