LG Optimus 2X getting updated to Android 4.0, but only in Korea
put a Q3 deadline on the update for the LG Optimus 2X which means that LG still has until the end of September to meet its original deadline. And while LG's tweet does indicate that the update is coming to the phone, the message refers to Korean units only. Still, the idea that the LG Optimus 2X will be getting Ice Cream Sandwich somewhere in the world has to give owners of the model elsewhere some hope that Android 4.0 will be coming to their device.
As far as the T-Mobile G2X is concerned, there is no indication that any change has been decided on and it would appear that the Stateside version of the LG Optimus 2X has finished its life with Android 2.3.4.
