hi
im new , first sorry for my bad english
it's my first test with an iphone ( im a pc reparator )
first i repaired , the dock of the iphone ( replacement part ) than the battery dock
the phone run with an ios 5.0.1 but signial is instable , and when you recive a call you can't speak or hear anything ( if you record a video speaker and mic work great)
second problem , is no the wifi ( gryed ... no wifi ) i have a bluetouth adresse but infinit serch , and in wifi adresse it's N/A
so i reflowed the wifi ic part ( first with heat gun , and after with a irda station ) no change
instaled the ios 6.0.1 ( wifi become desabled ) , downgrade to 4.3.3 no wifi no bluetouth
i show the pic if any one can detect a missing capaciotr or jumper that i can do
or how can i detect the bad capacitor or other element ( i have no wifi ic replacement than i try to repair this one )
