Iphone not ringing, clock not holding correct time and no wi-fi

Question

Man...I thought I had done something, but since the 2.1 update, my phone doesnt ring but for one or two random calls. The clock is also not holding time...it does if i restart the phone but within hours its back to hopping around, trying to get the right time. When it does stop doing that, the time is wrong.
On top of that, it cannot find any wi-fi connections.
Ive restored it to the previous back up and it doesnt do any of this.
Is anyone else having these problems since the update?

If those solutions don't work your iPhone 4s has probably developed a hardware problem. The permanent solution is to get it replaced.
You can search the internet for heating and freezing solutions that might work (at least for a while).

Root cause: On some iPhone 4s devices there may be a flow soldering problem with the WiFi chip. After long periods of WiFi activity such as installing an iOS update (for example, iOS 7 or iOS 8) there may be a connection failure. A work-around to this is the procedure in the youTube video.
