Though the Xperia Mini smartphone is a budget smartphone which was launched by Sony Ericsson. Sony didn’t even push a single official update for this device and it stayed on the Gingerbread firmware only. But there’s nothing to worry about, you can always update your device to the latest firmware. Special thanks to the FreeXperia project which is aimed to bring the latest update for the Xperia devices.
