It looks like the scare that T-mobile would run out of pre-order G1s was well warranted now that an official statement has been released by the carrier. A spokesperson said: “Given the great anticipation and the heavy pre-sale demand for the T-Mobile G1 with Google, we nearly tripled the number of phones initially available for delivery on our Oct. 22 launch date, and have sold through them all.”

So what does this mean for those of us who pre-ordered the G1 or plan on ordering?  Well first, the pre-order date has been extended up until October 21st, just a day before the official commercial launch across select T-mobile retail stores (3G coverage markets listed below).  If you pre-order the G1 today, you will not receive the device on October 22nd, but instead will receive your phone ‘at a later date’.  If you ordered your G1 before October 3rd you will have it delivered right on schedule ‘as early as October 22nd’.  The bottom line is that the safest way to get your G1 on October 22nd is to buy the device in store if you happen to be in one of the hand few of cities that currently has the carrier’s 3G network up in running.

T-Mobile’s UMTS/HSDPA high-speed data network is currently available across 13 major metropolitan markets: Austin, Baltimore, Boston, Dallas, Houston, Las Vegas, Miami, Minneapolis, New York (including northern New Jersey and Long Island), Phoenix, Portland, San Antonio and San Diego. The company plans to expand its service by mid-October to additional markets, including Atlanta, Chicago, Los Angeles, Orlando, Philadelphia, Sacramento, San Francisco and Seattle. An additional six markets — Birmingham, Denver, Detroit, Kansas City, Memphis and Tampa — are expected to have the network available before the end of the year, increasing the number of markets with T-Mobile’s 3G network to 27 markets.
