Old iPhone 3g with a short life battery

Моя проблема

My mother in law is barely using this phone properly, it would have been a sin to buy her a new one ;-)

Моё решение

Overall, pretty good, just at closing black ribbon cable labeled "1" and "2" disconnected or I did not connected them properly at first.

Also installing the new battery required attention: there are so many ribbon in the way, I first stick the battery on one of them, Oups...

Мой совет

Take you time, make sure to follow all the steps properly, voila!
