Just check out the U2 Guitar Archive. I don't have the URL off hand, but just do a search for it. The tab is on the site, along with almost every other song that U2 has written.
for the verses the chords are:
E G D
C G D-when you hear the chords change
then for the chorus
C G D Dsus4 D
for the break
