Does the CN version with flashed OS support 4gx which is avaialble on Telstra and Optus networks? I cannot seem to find the answer. See below for what I've found regarding this:
"From a compatibility viewpoint, if you want to get the most out of Telstra's phone services, you'll need a 4GX compatible phone, but you won't find that on many manufacturer specification sheets. That's because it's Telstra's marketing term for its specific carrier aggregation approach, which bonds its 700MHz and 1800MHz networks together on compatible devices. If you want to get the most out of Telstra's network, you'll need a phone that supports that carrier aggregation approach on those frequencies, although if your phone doesn't support it, you can still get 4G access, albeit at lower speeds."
