Hello,
I've got an iPhone 5 in black (16gb) which I no longer use. It's in good working order but suffers the usual battery problems (i.e. It's good for about 10 hours on standby and about three in use). The headphone jack is also broken so in all honesty it's not going to be good if you want it for music or headphone hands free...though it does work with bluetooth speakers.
I don't like hawking things in shops and I also would prefer this to go to someone who could use it and that they wouldn't have to pay shop premium.
Make me an offer! (I'll even take exchange offers if you have a bar/restaurant/shop...etc!)
Andrew.
