Ok lately my w580 has been having some screen conflicts so i called att warranty and there sending me a new one. I didn't really care about if it was under warranty or not and am going to send it back anyway. Before i debrand my phone again i wanted to know if i could back this phone up completly! if so how would i do it? Also if i do make a backup of the att firmware could i flash it to my current phone before sending it in?
