not looking to bid, as I already have an iPhone 4s, but you will have a bit more luck if you can put a bit more information and possibly rewrite the ad a little.
It's a white iPhone 4s on O2, then? Is it 16GB, 32GB or 64GB? Do you know whether it's locked to O2 or will work on another network?
Are you selling it with the SIM (and phone number) or without? What age is it? Do you have the box, cable, charger, etc? Are you open to offers or do you know what kind of price you're looking for?
Finally, I just want to say that I love my iPhone 4S and have no need or desire to get the rather oddly shaped iPhone 5 so I can heartily recommend a 4S.
Bruce; if you can get a few more details up then I'll tidy the thread up and add them to your original ad.
Cheers, and good luck in the quest for a new truck!
