iPhone 3GS Battery
Spoken like someone who would pay extra to be able to upgrade a phone every 6 months. Believe it or not there are still a lot of us who buy for the long term. For people like me self repair or local shops are the only way to go. I have had 2 phones in the last eight years and I really appreciate these tear downs. They can actually be a deciding factor in which phone I purchase.
You have obviously not worked all that much, I could be wrong but don't think so, with electronic devices. Usually it is not the miniaturized parts that go bad first rather the battery or the connectors. And these are parts that most people handy with small tools can replace.
