As promised earlier this month, Samsung is beginning to roll out Android 4.0 updates to all owners of the original Galaxy Tab line, starting with the GT-P7510 10.1-inch units released in the UK and elsewhere, according to SamMobile. While Samsung has yet to provide a specific timeline for Wi-Fi and 3G variants of its smaller tablets, like the Galaxy Tab 7.7, Plus 7, and 8.9 models, each is expected to receive a similar update to Android 4.0 as well. Users can expect the updates to be delivered via Samsung's KIES app or an OTA update.
