As the person that reviewed both of these devices, the Thrive and Thrive 7, here at Android Police, I felt something of a responsibility to post on this matter. On its community forums, a Toshiba rep issued the following statement on the status of the Ice Cream Sandwich update for its Thrive tablets:
We are working hard to bring Android 4.0, Ice Cream Sandwich to our Thrive tablets. While we originally estimated it would be ready this spring, we now estimate the update will be delivered to all Thrive 10” and 7” tablets by early fall. Apologies for any inconvenience and thank you for your patience.
