"For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God." (John 3:16-18 ESV)
"Rejoice in the Lord always; again I will say, Rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus." (Philippians 4:4-7 ESV)
I had this exactly same problem and told about it here before but then I realized that even though I worried and got frustrated about my iPhone 4S sounds not working God is always in control of everything that happens in this world. Even the problems in my iPhone are controlled by Him. Then I prayed that this problem would go away if it is God's will. The next time time I tried my iPhone sounds it worked just as before the update. But what comes to the subject of me having an iPhone 4S I have the same opinion as the apostle Paul says in his letter to the philippians...
"Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead." (Philippians 3:8-11 ESV)
