How long was he in 'phone detox'? From what I gather, only 2 months, which isn't nearly long enough. I've been 100% phone free for 4 years now, and was 95% free 2 years prior to that (only powering it on for work). I can personally say that anything less than a year is probably not long enough to even dent the addiction, and anything less that 2 won't teach you the discipline to stay phone free.
