Boxed factory unlocked Samsung Galaxy Note GT-N7000 will sell or swap for iPhone 4S !

I will either sell it for 310, or if you have an iPhone 4S on o2 or unlocked I will do a straight swap. My phone is in very good condition - it has had a screen protector on since new so the screen is perfect. There are some small marks around the edge and on the back but they are very very small, you would hardly notice them. It comes boxed with charger, headphones, case, screen protectors, USB cable and everything it came with when new. It is still under warranty and is totally unbranded and unlocked. It is running official Samsung Android 4.0 Ice cream sandwich. Ideally would like to swap for an iphone 4s, but will happily sell for 310 I am located in erith which is in south east london (near woolwich if you know where that is) and it takes around 25 minutes to get there from london bridge thanks
