LG has surprised just about everyone this evening, and released the Ice Cream Sandwich kernel source for the Optimus 2X. Word from developers is that this source also applies to the P999 (T-Mobile G2X) as well. This means two things -- one, LG is serious about releasing ICS for the 2X, and that the CM team can now crank out a much better CyanogenMod 10 build for the devices.
It's a little late, but better late than never. Look for development on these devices to step back up again.
