I found myself spending far too much time on my iPhone, and most of this time was spent using Safari and Twitter for mindless browsing.

My approach to this was to uninstall all "problematic" apps, especially Twitter. Then I used my iPhone's Restrictions settings to hide Safari, and to prevent the installation of new apps. I then asked a friend to set a passcode on "Restrictions" so that I was unable to reinstall Safari, Twitter or anything else even if I wanted to.

After a few weeks, I got hold of the passcode again (to install something "essential" :)) but I have never since reinstalled Safari or Twitter. The habit was broken. Result: no longer do I walk down the street browsing the news, nor do I find myself staying up too late browsing in bed.

It's been a positive change for me.
