My Optimus X2 was missing its custom android While I was waiting for my new LJ Optimus X2 (P999) mobile I watched a couple of youtube reviews and it always came with extra features to android. But my phone is pretty much vanila android. Is it because of my carrier? Videotron in Quebec. 

Features I am missing: From what I could see in videos there was a different keyboard more like the one from Ios. Also some features like taping the side of the phone to move the cursor around. Holding a icon and tilting the phone left and right to move it around. Pretty sure it had extra features everywhere. Also a lot more options in settings then vanilla android.
As far as I know (not from US/CA) the P999 is a T-Mobile G2X device with vanilla Android, whereas P990 is LG Optimus 2x. The specs are mostly similar but there are certain differences, such as the OS customization. Maybe a custom ROM will bring the functionality to the G2X as well.
