I had the very first Android phone that was released, the Google G1. In the UK it was also known as the HTC Dream as they made it for Google.
Also it didn't have a headphone slot even all the way back then, it came with a set of mini usb slot headphones that annoyed users, most Android phones returned to using headphone slots for many phones subsequently till Apple "invented" not having them as standard a decade later.
Still have it in a drawer and with the quaint slide out keyboard seems they're fairly valuable to collectors for such an old and redundant phone.
