On topic, I have LTE, 36% left, 18hrs 15mins on battery, 2.5hrs screen on time, but I use Voltage Control underclocked @ 1350MHz
I think we have different definitions for 4G. The definition I'm using is the same definition all U.S. carriers use. T-Mobile & AT&T advertise that they have large 4G networks which is true. Also, LTE is never advertised as just "4G". They always include the "LTE".
Maybe the term "4G" is only used for LTE & WiMaxx in Australia.
