Apple iPhone 2G - 8GB Locked

I am selling my first iPhone. 2G - 8GB
I bought this off ebay 3mths before the first iPhones were released in Australia, I probably used it for 6mths tops. I havent used it for ages because I replaced it with the 3G so it has been in its box ever since. I had no problems when I used it. It has 2 tiny scratches on the silver near where the silent switch is and a tiny scratch on the left hand of the screen, at the bottom.

It comes with headphones that have never been used, a docking station and a USA AC charger port (I think!) but I dont seem to have the USB cable but one should be able to be purchased for next to nothing.
Model #A1203
It is locked & not jailbroken as I was never any good at doing a jailbreak for each update of software that Apple released but for someone who is computer minded, it should be a breeze & should be able to update it to the latest version.
At the moment, I think it is restore or recovery mode, (There is an Apple symbol on the screen). As I mentioned before, if anyone knows how to unlock it, it should work as good as new.
If you have any more questions, please contact me via email or 0410 340 159 and I will try to explain further.
Please contact me for an idea on postage.

Thanks for looking
