The Galaxy Gio made its Canadian debut in August 2011. Initially available to Bell Canada, the Gio was soon made available at Virgin Mobile Canada and Solo Mobile. Starting in December 2011, the Galaxy Gio was also made available in the United States, as the Samsung Repp on U.S. Cellular.
The device has a 3.2 in (8.1 cm) HVGA multi-touch, capacitive touchscreen, a 3.2-megapixel camera with auto focus, and an 800 MHz Qualcomm MSM7227 Turbo (ARMv6, 278 MB RAM, 158 Mb internal storage, 3G HSPA+, FM Radio, GPS, Wi-Fi 802.11 b/g/n, and a 1350 mAh battery. 
The Galaxy Gio originally came with Android 2.2 Froyo, with Samsung's TouchWiz user interface but users can upgrade to Android 2.3.6 via Samsung Kies and by now (October 2012) Android 2.3.6 is preinstalled on many Gios sold throughout the world. Changes that are brought by the 2.3.6 update is a new lockscreen, new phone icon, the blue glow scrolling effect and a few other cosmetic changes around the System UI. Android 4.1 for Gio has not been made available by Samsung yet due to the less powerful hardware,[when?] though an upgrade is possible via Root and ClockworkMod Recovery.
There is also a port of the AOSP-ROM both ICS and JB available, made by MaclawStudio which is bugless and stable.
