As you’re already aware, Samsung initiated the Android 4.0 rollout to many of its devices. As some of their smartphones and especially their tablets have seen a taste of ICS, others have yet to see the update— and that’s why Sammy announced the rollout of ICS to the Samsung Galaxy Tab 10.1 (GT-P7500). While this is indeed exciting news, please keep in mind that the update is for P7500 users in Italy only at this time, but the hope is that the update will soon be rolled out to owners of the device in other markets.
If you live in Italy and own the tablet, you can use Samsung KIES or OTA for this update— but make sure the WIFI is on if you plan to update via OTA. Those of you GT-P7500 owners in other markets just sit tight, the update should be on its way sooner than later.
