Sony recently assembled a list of devices set to receive Android 4.0 and spilled the details on which devices were next in line to receive their dose of Ice Cream Sandwich. It appears that Sony is keeping up with its schedule, as both the Xperia arc and Xperia neo’s respected push to Android 4.0 are now live. Sony does make note of “minor differences” in firmware depending on your device’s region. The company offers a solution to discover exactly which firmware version your phone is receiving by checking its Sales Item (SI) number, which can be located behind its battery.
For a complete list of SI numbers by location, be sure to visit the source links below. However if you’re not looking for details and only looking for Ice Cream Sandwich, try your phone’s settings to initiate the update if you haven’t received an over-the-air notification yet.
