Also, I tether through USB all the time but find it to gives me a lot of connection reset errors in the browser. So I'd rather have real supported tethering I think.
For now I think I'll just be optimistic and wait for LG to come out with an update.
I tend to agree with you. Without WiFi hotspot enabled, the Optimus Quantum has an extremely low SAR rating (.86 or lower, I believe). Other WP7 devices had higher initial ratings and were still able to enable this feature under the same standards and regulations. Now, it is possible that the C900B has hardware just different enough to make it impossible, but I'm sure there must be a way for them to throttle the output from within the firmware... At any rate, even though they outright told me that there is no chance of getting it (on the C900B firmware, that is) officially, I haven't completely given up; companies often say they can't/won't to cover their behinds. Still, I plan to upgrade when my contract allows me. SaskTel's new WP7 device is SMOOOOTH... I will miss the physical keyboard, though...
