I've got a a brand new and sealed iPhone 3gs 16gb that I bought off a friend for £400 smackeroos. I tried to get a contract for it, failed miserably as I don't know which company it's with or whether it's unlocked, went away the next day for a week.
While away, I used a friend's iPhone, couldn't use it to save myself and have decided not to bother opening it.
I've decided to sell it for a loss on here instead of eBay as I want a quick sale.
Thanks guys :)
