I have an iPhone 2g.
I have it for 2 years...
everything was perfect... version 3.1.2, suddenly i had a grayed wifi.
I understand that the only way to fix it is to downgrade to 1.0.2 or older, but whenever i try downgrading from 1.1.1 to 1.0.2 it stuck on "waiting for iphone". I tried i brick and apptap, nothing...
The time i "played" with the versions, it lost its sound also...
can anyone help me please ?
Gray wifi can be caused by either software or hardware.

Other causes can be corrupted baseband or various hardware problems - these normally can't be fixed via software.
