How Do I Fix A Broken Antenna Wire/ iPhone turning on and off

Hey guys I was wondering if I can replace my antenna wires for my iPhone? I was tearing it down to replace the battery and noticed that the wires under the black cover were broken. One was right at the connector piece and the other was broken right in the middle. Should I reconnect them somehow? Also my phone keeps turning on and off on its own. Please advise me on how to repair these issues. Thanks

you can buy replacement antenna's on ebay, i don't think they sell them here.

what are you doing when phone turns off? this might help to pinpoint the problem

Update

it sounds like the battery is shorting.or worse the (sorry for lack of technical term)power processor. check that the 3 wires from the battery are soldered correctly to their right spots and that no solder is connected to another spot.

don't suppose you dropped the phone right before it began behaving badly? i had similar symptoms on 3g phones from that.

can you put it in restore or DFU mode and try to restore?

Well when this first started a friend of mine told me to leave it on the charger for a couple of days and that it might work... nothing changed. Then another one of my friends told me to change the battery cuz he did it to his when it started to act up. so before I attempted this I wanted to see what kind of error code it would throw up and it was (20000). I don't know what it was for so decided to go ahead and change the battery. The wires broke in the process and now my screen doesn't recognize anything. It just comes on and that's it. When it keeps turning off and on I can't do anything until I plug it in to either my comp or dock. When it does turn on and off it won't go past the apple
