Apple iPhone 4S 64GB - Officialy Apple Unlocked - 3 Months old - As new condition
For Sale: iPhone 4S 64GB (Unlocked) This iPhone is only 3 months old and is in "as new" condition. The phone during this period has always had a front and back screen protector on it and used in a case so the phone is completely mark and scratch free, simply like new out the box. This phone was bought under O2 contract but has now been unlocked. As described to me by O2 and on the Apple support page (titled - iPhone: about unlocking), now the phone has been restored back to factory settings the sim you now activate in it (which ever company i.e. vodafone,EE, 3 etc) when you first switch it on will be who the phone locks to. This phone is therefore unlocked and you can choose whichever provider you wish to use. The headphones (incl volume buttons and mic) have never been taken out of the box and the charging cable/unit has had only very light use, again looks as new and is still in its original wrapping. I live in Brighton and work in Westminster (London) so am flexible on where you can colect from. Please contact me if you have any questions. Please note, this is for collection in person only, I will not ship.
