Don't know if somebody already beat me to it but has anyone noticed what the power mode in the settings menu does?
High Performance = 4G/3G/2G and whatever brightness you set you screen to
Normal = 3G/2G + Automatic Data Radio timeout when phone sleeps and whatever brightness you set your screen to
Economoy = Voice Only and whatever brightness you set your screen to
Just an FYI instead of going through the wireless networks menu to turn off 4G.
Only thing that sucks is they don't have a High Performance Normal Mode combo that allows 4G/3G/2G access Plus automatic Data Radio Timeout...
Just putting it out there just in case it hasn't already been covered...
