So.. is there any kind of solution to the problem?

Had this problem before. I replaced the light sensor and earpiece flex and it worked again. It only cost a few £'s on ebay.

I only found it by getting the dimesions off another motherboard with the compenent still on.

Don't know if it is the right values if anyone could confirm its the right values i'll all order a few up, as i have to make an order to dgikey for a few other things.

EDIT:

I have now ordered and fitted this part. Woking fine. If anyone wants one i can ship one out to you. PM if you want one. I only have 25

Hi.
I have Iphone 3G always signal drops. It seems someone tried to repair this iphone before me. He bended lower part of logic board as shown on picture.

Small part shown green rectangular is cracked. That crack is too tiny. Is there any other place where I can make jumper short connection for that? Also I short connected red dotted part because small inductor is ripped off from there.
