It doesn't work!!! I have an iPhone 4S. And I'm calling apple tomorrow!

I know, I know, this has been eluding me as much as it has you, my apologies.

From Digitaltrends.com :

• Some people have had success by removing an apostrophe from the iPhone name. If your iPhone is called something like “John’s iPhone” then this might work. Go to Settings > General > About > Name and change it to something with no apostrophe.
• Some people have reported success by putting the iPhone into Airplane mode and then going to Settings > General > Reset > Reset Network Settings, but the problem may return.
• You could also try going to Settings > Control Center and disable Access on Lock Screen then turn your iPhone off and on again.
• Make sure that your router firmware is up to date.
• Try backing up your iPhone and then restoring it. Check how to factory reset an iPhone for details.
• If nothing is working for you, try contacting Apple or take your iPhone into an Apple Store.

Ok I know this is not what you may want to hear but if you go to settings general and about and look at wifi it will be blank. The wifi card has gone out there is no software fix for this it is a hardware issue

If those don't work, I think it's time for you to take it to your nearest apple store, and see if they will replace it.

No, he is referring to your iPhone's "Wifi card", a chip inside your iphone allowing it to connect to wifi.

In the about portion it tells you the wifi cards info also know as the MAC address if it is working it will always show a long string of characters

I think this is a problem select to the iPhone 4s, let's try the heat thing xD.

Yeah we have different names and profile pics....
