re: side note: I'm assuming you ripped off the copper strip from the mid-plate that connects to the rear facing camera. Yes, I would replace that, and don't forget to put the little silver cap back on top. If you ripped some cables ^, it might be worth while to pull that wifi cable out and go over it with say (what I use) a 30x jewelers loupe. Even a small tear in the cable can be missed with the naked eye and can make all the difference in the world. If everything pans out there try "Forgetting" the networks that you have previously joined, in your Wifi connections, and then re-connect to them. There could also be just a coincidence, where someone could have a microwave next door, your router is on channel 6, and its getting interference. Also make sure your device has the latest IOS updates.
