Some leaked screenshots of Best Buy‘s inventory system reveal the ship dates for a few upcoming smartphones, including an unlocked Palm Treo Pro, T-Mobile BlackBerry Pearl Flip 8220 in red and the T-Mobile G1. All three are listed as arriving in Best Buy stores as of October 26, though the T-Mobile G1 will apparently not be sold by the electronics retailer until November 16th.

The G1’s previous release date was pegged at October 22 by T-Mobile, giving the carrier about a month‘s head start over Best Buy. The Best Buy inventory screens did not reveal pricing information for the handsets. [via BGR]
