An iPhone that freezes on the Apple logo can be a puzzling problem. It usually happens when you have just done things like updating your iOS, restoring backups from iDevices, or after installing a new app. To make your device return to its normal condition again, there are several things that you can do. You can either put the phone in the DFU (Device Firmware Update) mode, which completely restores your iPhone, or use ifunbox to detect and delete problem-causing apps.
