LG G2x / Optimus 2x
There was conflicting info out there on that very issue. We went back and forth with LG and T-Mobile about it, trying to get official confirmation. We didn't publish our specs until we got it sorted out.
The final word I received is that it will NOT have WCDMA 850, nor 1900. T-Mobile is in the process of updating their web site to show the correct specs.
