Nice conversation, but as for penetration qualities 1700mhz does a better job than 1900 and thats why is makes more sense for tmobile to release LTE on it first...

Not quite. The "1700 MHz" convention is something that Phone Scoop and other outlets have used to refer to AWS, and it is problematic for the many who do not know wireless spectrum very well.

The proper nomenclature should be AWS 2100+1700 MHz because the downlink is in the 2100 MHz range, the uplink in the 1700 MHz range.

So, AWS 2100+1700 MHz is a mixed bag. Yes, compared to PCS 1900 MHz, the AWS 1700 MHz uplink has a slight propagation advantage, but the AWS 2100 MHz downlink is at a slight propagation disadvantage. And if the downlink drops due to propagation issues, the uplink is rendered irrelevant.

Thus, empirical experience suggests that AWS 2100+1700 MHz, propagation wise, is mildly inferior to PCS 1900 MHz. The advantage that AWS 2100+1700 MHz offers is more open and available spectrum.
