A few days ago, my iPhone 4 has randomly stopped connecting to the networks it used to successfully connect on iOS 6.0. I decided to restore it to iOS 7, after that, i have tried to connect it to the same network, and it miraculously worked, but after a moment it randomly turned off the Wi-Fi and the same message has showed, I have tried everything i could to make it work, but then it started refusing to connect to other networks. I wanted to grab something and accidentally knocked my phone off the desk, and it landed on a hard part of my desk chair. It bent my phone's back glass protector, revealing old cracks. I tried to fix it or put weights on the bent part, but it wouldn't budge. If I took off the protector, the whole back would come off and make it worse. I think there is nothing i can do anymore, i'm concerned that if i keep trying to use my iPhone 4, i could just break it. My decision is to leave apart the phone and never touch it again since i'm guilty of doing this horrible act. I'm sorry... Goodbye
