The latest firmware (.184) or whatever is giving a lotta probs to ppl with wifi n all. can we upgrade xperia u to ics n keep the older firmware (.15x) or whatever is the default stable one? that may giv all the benefits of new android with none of the issues ppl hav been facing. so does any1 know if we can update android and not update firmware?
