The Android Guys have dug up some juicy gems about the Google G1 Android phone. First, they find some engineering drawings of the device, and then they stumble upon a TV advertisement for it. This is some good stuff.The engineering drawings found by the Android Guys are nice to see, but they don't necessarily represent what will be the final version of the hardware of the G1 phone. Even so, the drawings shed some light on possible features of the phone.

According to "a trusted source," there are some interesting surprises seen in the drawings. The Android Guys write, "One noticeable difference is the slight tilt to the bottom of the handset where the trackball is located. Although it's a small change, it's worth noting. We love the 5 row QWERTY keyboard with the spaced out buttons... We're curious to see what that 'menu' button is for as well... Check out the back of the device where it shows 'With Google' on it. It tells us that T-Mobile and HTC are using the brand recognition to help sell the handset."

The dimensions of the device found in the engineering drawings match those revealed by FCC documents. This consistency lends an air of authenticity to the engineering documents.

Hitting us with the second of two sucker punches, the Android Guys have the inside scoop on an upcoming television commercial for the G1. They say the information came from someone they believe to be an employee of the agency that is making the commercial (who would probably be fired for sharing these details).

Here is a summary of the commercial:

• Setting is after hours in a computer/science lab • A cell phone sitting next to a computer starts to pull all kinds of information from the PC • Bright lights flash and room goes dark, silent. • Janitor or security guard walks in with flashlight to check on disturbance • We see his face light up from phone's perspective • Google logo is shown in commercial • The G1 phone is not actually shown in commercial.

Whether or not these details are genuine can't be confirmed. The blogosphere is speculating that the G1 will be announced no later than September. With CTIA falling in the second week of the month, HTC, Google, and T-Mobile have the perfect opportunity to announce their newest darling to the world.
