It's a 'wot's hes got in his pockettes?!' pic! Here's another one where you can see that the Edun jeans Bono's wearing has writing (some sort of poem I think) inside the pockets....
With that short black hair and those black-rimmed shades, I always think he looks like Elvis Costello. Elvis went through quite a Bono phase at one time. Haven't seen him for a while so I am not sure if it's still going on!!
whoa... ^^ I was in the process of posting those 4 pics at this minute, before I hit post I checked to see what you had just posted and it was the exact 4 pics.
