Hey guys im still on 4.0.0 and well i just want some reassurance i guess. I was sitting on my couch with the phone beside me(cuddling) lol and well i looked at the bars and it only had 1 bar then 10 mins later i look again to check time and i had full bars...now do signals doo that? also kindof a totally different question. Is it a fact that Apple is slowly fixing the problem with the new iphones coming out? if so can i get mine replaced?
