iPhone 3G! Pristine Condition!
I’ve recently purchased the iPhone 4G. Therefore, my 3G must go!

CONFIRMED T-MOBILE COMPATIBLE! I’VE TESTED THIS WITH A SIM CARD PERSONALLY ON 8/22/2010!

Specs:

Genuine Apple 3G 16GB
Other than purchasing and switching cases this iPhone has lived in it’s cases. Therefore the phone looks new. 
The digi-touch screen has been replaced very recently. Therefore the screen is flawless and resembles a brand new 3G.
There is a minor bump in the top right corner, along with hair-thin scratches near the USB plug-in. Both are hidden in a case.
The Apple logo on the back is like new due to constant protection in the case.

Comes with:

iPhone 3G 16GB
Apple brand white USB cord
Apple brand headphones (non-mic, outbound audio only)
