I'd like to see the metrics on how many streams are being delivered today for this press release as I've seen a lot of congestion, this from one of their edge providers: edgeboss.net

The G1 seems on paper, and video to be the first real challenge to the iPhone with the added benefit of a full qwerty keyboard for those of us who have been hooked on the Blackberry.

According to Cole Brodman. Chief Technology and Innovation Officer at T-Mobile, the G1 will see its commercial launch on October 22nd.

Some other important information to know about a T-Mobile contract:

The unit will retail for $179.00
The company will offer two tiered plans for data and messaging
$25.00 per month for unlimited web with some messaging
$35.00 per month for unlimited web and messaging

When I spoke to a company rep however, I was told the G1 would fall into the same category as other HTC units, namely $19.99 for what they call Total Internet.

You have 30-days to try the phone or return it
You have 20-days to accept the contract

Some other questions on the technical side include how well the 3G network will work as there are 21 planned cities and two regions. Metropolitan areas with T-Mobile's 3G - coverage by October 22, 2008:

Atlanta, Austin, Baltimore, Chicago, Dallas, Houston, Las Vegas, Long Island, NY, Los Angeles,
Miami, Minneapolis, New England, New York City, Northern New Jersey, Orlando, Philadelphia, Phoenix, Portland, Sacramento, San Antonio, San Diego, San Francisco and Seattle

T-Mobile has had a reputation of offering lower cost at the expense of voice and reception quality, this from the people I know who have had their service over the past two years. While I would expect an improvement over that time, working in the canyons of New York City I can attest to call quality issues with both Verizon and AT&T who have more robust networks.
