I am selling a IPhone 3GS, 32GB, UNLOCKED to all networks which is in good condition .It will come with the original box, charger and case. I have had it for a year and am looking for a upgrade so want to sell it fast as possible for the price of just 160(open for reasonable negotiation). Some extra information about the condition of this phone is that it has a small crack at the back and a small scuff at the top, both not very noticeable. Otherwise in pretty good condition. If you need any more information regarding delivery or local pick, Any extra picture or if you want my phone number just drop me a email. Thank for viewing.
