Hi,
i have an iphone 3g with a non working wifi. it s not grayed out. i can turn it on/off. but it finds no networks. i tried to install different firmwares but it would not work.

APPLE iPHONE 3G OEM WIFI NETWORK AERIAL ANTENNA+FLEX US - eBay (item 390016643489 end time May-11-09 03:55:28 PDT)

there is such an item, i can manage to replace, i have some experience.
do you guys think replacing may help? or can you suggest me a way?(a repair service would do, but i dont live in us)
thanks
