WiFi doesn't work properly on iPhone 2G after battery change
I have a problem with WiFi after I changed the old (dead) battery to the new one in service center.
The problem is that now iphone's wifi cannot see the AP within 2-3 meters. If it sees AP - I have only 1 strip of signal on my iPhone display and it often turns into EDGE. So the work with Wifi is almost impossible.
My question is - what can be wrong with iphone signal? I think the crooked hands of serviceman occured. Probably, some contacts or conductors were affected.
How can I fix this problem? I'm interesting in technical details. Is it possible to solder the conductor to the right place or I have to change the communications board?
