Looking to swap iPhone 4s for Samsung galaxy s3. 3 network +

Got a white 16gb iPhone 4s on the 3 network, looking to swap for a Samsung galaxy s3 in white and either on 3 also or unlocked. Phone is in excellent condition, and has been kept in a silicone case. Just fancy a change. This box contains 2 phones, master and a secondary (you only need to plug one into your phone socket, the other can go anywhere there is a power socket). These are great for use in the home, clear blue backlit screen, many features including speakerphone, 11hrs talktime, multiple ringtones and alerts, 300m range - all in all spot on for the price. These have been used for less than a week (while we waited for some new phones to be delivered to our office). Unfortunately the box is slightly damaged - torn when opening, but the phones are absolutely fine. Currently selling for around the 25.00 in Argos, Comet etc... Thanks for looking hi i have a blackberry bold 9900 in white. it is in excellent condition. the phone comes with the box, charger, usb and the headphones. it is in outstanding condition. it is also unlocked to any network. no time wasters please... i am selling brand new lg gm 360 mobile present for wife but prefers her old one as she is not into new technolgy this phone has been unblocked costing 10pounds it is not used and i think their is still credit on phone Features: 8.1 Megapixel camera Slider type phone Touch screen on selected apps.
