I've got a iPhone 3G 16GB for sale.
It is Jailbroken, but I'm on iOS 3.1.2 with baseband 05.13.04.
Only selling as I've upgraded to a iPhone 4.
In good condition (screen is in great condition, it's just the back that got general wear - nothing serious though).
If your interested let me know and I can send you some pictures. I live in Hertfordshire by the way.
Im happy to take £155 delivered (royal mail recorded) - Otherwise it's just going to be sitting in a drawer.
I've just found this website after a little bit of googling, so let me know the t&c's for payment / delivery.
Would prefer to buyer to collect.
