T-Mobile G1 lacks a 3.5mm jack
T-Mobile G1 got official making a lot of noise around here, but wait is the noise worth it? Look at the previous post and you’ll see full list of T-Mobile G1 technical specifications and among them you will notice lack of one of the most important things in phones.

Amazon store has 6 milion DRM-free songs for T-Mobile customers, but HTC made G1 just doesn’t have 3.5mm headphone jack available for you to listen that music.
It seems that’s an old problem with the HTC. They tend to forget about the music jack in their models. The Touch HD is the only exception so far.
That means you should buy an USB dongle to mediate a connection between your faithful headphones and the G1. And the adapter won’t arrive by the time the G1 gets released.
