Swithing to "lte only" mode.

[2008xpress]

Before the jellybean update I was able to lock many phone into 4 g only via the phone info app. This was very useful because I live in a fringe area and when left in cdma/lte mode it would never hold the 4g signal. Has anyone figured out a way to do this after the JB update.?This was the only way I could even attempt to watch video on my phone when at home. This sucks !
