However, the release of this update will not be uniform since Sony will release them in groups.
To check if you are eligible for the Sony Xperia Mini Android ICS update, you will need to find out your smartphone's “Sales Item Number” which is an eight-digit number present at the back-end of the device below the phone's battery.
After determining this, you will need to check if the Sales Item Number matches with the devices listed for receiving the ICS update on the Sony website.
The previous Sony smarttphone to receive the ICS update was the Sony Xperia S.
