The Samsung Galaxy mini and Galaxy Gio are both getting Gingerbread in its 2.3.3 flavor, but if you can't wait for the official OTA to hit your handset, feel free to head to the source link below to get an image of the beta firmware and detailed instructions. After downloading the XXKPF update for the Galaxy mini and the XXKPA update for the Galaxy Gio, you can flash it and enjoy all the benefits of Gingerbread.
With their humble specs, the two handset also prove an important point – hardware seems to be hardly a restriction for the update. A good argument to have in mind if you don't get your high-end Android updated, isn't it?
