OK, after part exing my iPhone 4 for a 3GS.
Mine is a mint 16gb model, which has had an invisible shield on since I got in in July last year. It was ordered directly from apple at a cost of £499 (Apple receipt can be provided), so is factory unlocked.
Comes with original box, which includes all the usual accessories (the headphones are unopened).
I'm going to be quite specific about the 3GS that I'm after.
It has to be "properly" unlocked; no jailbroke units locked to a specific network please. Any capacity will be considered, as will any colour. Cosmetic condition, has to be excellent - no scuffs etc on back, and screen to be free from scratches. Basically, it has to be a minter!
As mine still has part of it's original warranty remaining, my plan was to upgrade the AppleCare to give me another year with it. Therefore, I also want the 3GS part ex to still have warranty remaining, so that I can upgrade the AppleCare for another year.
So, money wise, for my mint, unlocked iPhone 4 with warranty remaining, I'm looking at £215 cash plus your mint, unlocked 3GS with warranty remaining.
