I got the official update to Android 4 on my nexus S sometime in April, and at first all was great. Then, slowly, my phone lost wifi. It will not even turn it on; when I press to enable wifi, it just turns it right back off. The phone also refuses to turn on data as well, so I can not connect to the internet at all. Thinking I could solve this with a recovery, I chose to factory reset my phone, This did not fix the problem in the least, but it DID delete all of my apps and personalizations (obviously), and with no wifi/data I have no way of getting any of it back. My keyboard also began acting up shortly after... sometimes I will press the keys and the autocorrect selections come up, but no letters appear in the space where your message is composed, and my "invisible" message can not be sent. I assume this is related? Please, help!
