wi_fi problem, no wi-fi
Hi, my iphone 4 has no wi-fi at all, Wi-fi button is gray in color and seems a little bit of dim. no restore or update helped. the original IOS was 4.0.1 now it is 4.0.2 tried restore several times but no results. so in this case should i return phone to apple store or should i replace wi-fi module? (if possible), need your help and advice. thanks.
Is this a good question?
