There' s only one first time...

Mi Problema

Putting a new battery on my 3GS

Mi Solución

It took me over an hour to disassemble my iPhone to change the battery and reassemble it: it was my first time.

But... wait... my camera didn' t work!!!

I did it all again, more carefully this time - especially putting the camera module back in place - and at the end it all worked fine: and it only took me TEN MINUTES! :)

Mi Consejo

Be very careful but don' t be too scared: you' re doing what a professional does many times a day
