Although Android 3.1 update for Acer Iconia Tab A500 made its international debut yesterday, Indian users will have to wait for some more time. International roll out is expected to take almost a month to reach every user.
On the other hand, the situation for Indian users is altogether different. According to TMI, Acer India is saying that due to the lack of proper support by telecom operators the OTA roll out has been deferred in India and will probably come via a software update tool. But it seems a bad excuse because HTC devices have always got the OTA updates in India.
Anyways, Indian users will have to wait for late July or early August for the update.
Update: It seems some of our readers have got the Android 3.1 update in India.
