3gs Wifi Greyed Out After Restore
I could do with some advice. Here's my story:
I have an iPhone 3gs 3.1.3 firmware 05.12.01 baseband that was jailbroken with Spirit. I had a disaster the other day and dropped the phone in the bath.
After the phone had dried out the phone put itself into recovery mode and told me to connect to itunes. I have itunes 9.2.
The phone did a restore and upgraded to iOS4.0.1 and everything now workd except my wifi. When I look in general settings, Wifi is greyed out and it says "No Wifi".
I now have a 3gs which has 4.0.1 firmware and 05.13.04 baseband.
I have tried the following:
1. Downgrading to 3.1.3 - still no wifi
2. Resetting Network Settings (firmware 3 & 4) - still no wifi
3. Restoring the phone from a backup in Feb - Still no wifi
I know I have lost my jailbreak and believe having read around that the most likely cause of the issue here is not a hardware failure (I should add that I have seen had wifi working but it was for a matter of hours before it died again), but most likely is caused by a corruption of the baseband.
Since I don't have any way of connecting to the phone besides via the cable because the phone is not Jailbroken, I don't know what to do.
Can anyone suggest anything or can anyone recommend somewhere for me to check?
