The recent discovery of a sizeable reactor angle theta(13) by Daya Bay and RENO has ruled out exact tri-bimaximal (TB) lepton mixing. Recently two of us studied the vacuum alignment of the Altarelli-Feruglio A(4) family symmetry model including additional flavons in the 1%26apos; and 1 %26apos;%26apos; representations, leading to so-called %26quot;trimaximal%26quot; neutrino mixing and allowing a potentially large reactor angle. Here we show how such a model may arise from a Supersymmetric (SUSY) Grand Unified Theory (GUT) based on SU(5), leading to sum rule bounds vertical bar s vertical bar %26lt;= theta(C)/3, vertical bar a vertical bar %26lt;= 1/2(r + theta(C)/3)vertical bar cos delta vertical bar (these predictions are based upon the assumption of a Georgi-Jarlsko
