iOS4 on 3GS - No WiFi
Everything went as planned but once the restore and sync finished I noticed that the WiFi field in Setting was grey out. I went to General/Network and also there it was grey out. No on/off switch.
I tried another restore. Same result. I have reset the network. Nada.
All the rest of the network connections work properly, including bluetooth.
I exclude an hardware issue because right before the installation the WiFi was working perfectly. I have searched in various forum but it seems I am the only one with this problem. Any idea?
iPhone 3GS, iPhone OS 3.1.3, from 3.1.3 to 4.0
