The phones we sell are what we would call A condition. This means that the phones are in perfect working condition and may show some light cosmetic signs of use but nothing really noticeable. All of the phones are fully tested and parts replaced where neccessary.
When you receive your iPhone you will also receive a warranty card. On this card is a phone number for you to ring with your IMEI number (from your phone) and your phone will be covered under a 12 month warranty. If there are any issues you can then ring this number and they will repair/replace the phone.
