can not get wifi or bluetooth

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

If they do not resolve the issue, this indicates a serious hardware failure. Take the device to Apple for evaluation and possible replacement.

Hi, I had the same problem on my iPhone 4s, after all imaginable resets and sugestions, Apple gave me a new one. Problem solved.

After 12 months?
