I have my iPhone 3G 16GB Black for sale.
It comes complete in its box with instructions, sim tool, mains charger & usb cable as well as a PDair Leather case, a third party dock and additional USB lead, unused 3rd party car charger, 3rd party stylus and two spare screen protectors.
I purchased the phone off of Ebay about 6 months ago in excellent condition. As soon as I got it I replaced the screen protector and as it has had one on since new the screen is immaculate. The silver bezel has small marks on it as would befit a phone some 18 months old. Apart from one or two 1mm scuffs, the back is in good condition too. Upon closer examination there seems to be two small hairline cracks one by the silent switch and a small one by the connector at the bottom. They do not affect performance though. It is overall in good condition.
In regards to the phone itself, it is 3.1.2 fully and officially unlocked and currently jailbroken. I can leave it jailbroken or I can install the new 3.1.3 firmware.
Remember that as this is officially unlocked you can upgrade to the latest firmware and still use ANY sim in it.
I can confirm that it works on all networks.
Bank Transfer preferred, although will take Paypal if you cover the fees.
As for trades, I do not need another phone as I am getting a new one on contract next week, so all I am looking at is a p/x with an LCD TV or similar, 19" - 21".
included Tmobile PAYG sim with 10 credit on it.
