My iPhone4 started only charging sometimes, and shortly after not at all. So I assumed the charging port was bad and ordered a replacement.
Little did I know that to replace the charging port you have to take EVERYTHING apart. This was the first time I've ever taken an iDevice apart and I was able to successfully do it with the iFixit tutorial. Else I don't know how I would have ever done it!!
Something that shows how to put it together. I know it's simply reverse engineering but the batterie connector to the charger is pretty darn hard to get back in with a pair of tweezers.
