IOS 7.0.2 upgrade broke wifi

Hi

After updating from 7.0.1 to 7.0.2 my wifi has stopped working. It will search for networds but when you click on the SSID it just says unable to connect. I have tried to connect to my friends wifi as well still won't work. I have restored my iPad back to factory settings as well as doing the "reset network settings" in airplane mode which some people have reported to fix the problem but still no wifi !!

Dose anyone know it Apple are letting people downgrade to 7.0.1? Going to search for the ipsw now to give it a go but any other ideas please let me know.

Thanks in advance
