A little known problem that occurs with a huge number of iPhone 4 and 4s models, is a malfunction of the wifi chip on the mainboard of the phone, causing the option for wifi to appear greyed out in the settings. We receive a huge amount of phones with this issue, which is caused by, (without trying to bore anyone to death with the reasons) heat on the mainboard which causes a connection loss between one of the BGA chips responsible from wifi and Bluetooth, and the board itself.

This can unfortunately happen to any iPhone 4 or 4s that is almost brand new or immaculate, but it can also never occur to the iPhone 4s which is alot older and worn, it is quite random.

One of our engineers can repair this iPhone 4s wifi issue in a few hours, with a 6 month warranty, as seen with this phone.
