In theory yes, but I did a beautiful solder on mine under a magnifying glass. The battery percentage wasn't reading right and like I said before, I had a carrier problem after soldering. My guess is some kind of interference or short circuit in the motherboard. So like LEE FORGET suggested I replaced the motherboard. Down here in Brazil the mother board cost me 50% of the original iphone price. But I figured it was better to fix it than let it go to waste. Working fine now.
