I updated my iPhone 4s to iOS 7, but now the WiFi and Bluetooth settings are grayed out and not working. I also need to know the procedure for deleting downloaded apps to free up memory on my device.

The issue with WiFi and Bluetooth being grayed out on an iPhone 4s is a known hardware problem where the WiFi chip's solder joints can fail, often triggered by the heat of a software update. First, try resetting your network settings by navigating to Settings, General, Reset, then Reset Network Settings. If the problem persists, it likely requires a hardware repair or device replacement. To delete apps and free up storage space, press and hold an app icon on your home screen until it starts to shake. Tap the delete icon on the app you wish to remove and confirm. You can also go to Settings, General, Usage to manage your storage more effectively.
