"The udpdate to Android ICS offered for free by Sony to the Xperia smarphone users has caused plenty of troubles. Not only the decision by Sony of not updating Xperia Play phones to ICS caused rage among customers, but those who were lucky to get an upgrade for their smartphones discovered that WiFi connection did not work anymore. Up to now, the only suggestion proposed by Sony to fix the problem is to turn off the encryption, and reboot the smartphone and the access point."
