T-Mobile today unintentionally showed its hand by posting an image referencing its G1 Android phone on the My T-Mobile website. The link accessible to subcribers confirms the design and name of the phone and is also redirecting customers to the currently empty T-MobileG1.com website. It likewise validates the existence of a black model rumored alongside brown and white versions. The news compounds a string of leaks that have revealed nearly all details of the 3G-equipped, touchscreen G1, which should be announced next week and released in mid-October for $200 on contract.
