I have a iPhone 3Gs in white available. This is the 16Gb version. I only used this phone for about a year until I got my iPhone 4. The screen is perfect and has always had a screen protector on since new. The back is pretty much spotless apart from a little mark/crack in the plastic by the docking port on the bottom, it has always been kept in a silicone case and hasn't been dropped so not sure where that has come from. This phone is on the O2 network, and I haven't tried to unlock it or anything. It will come with it's orginal box, cables, plug and headphones that haven't been used (I have put the new ones from my iPhone 4 with it). I bought this new from the Apple store in Bluewater about 18 months ago for £450. Also can include the Belkin silcone case with the phone if buyer wishes.
These seem to be selling on ebay from anything from £150 to £200, so offers in that region please, plus delivery.
