Samsung Galaxy S3 White 16gb Mobile Phone brand new unwanted upgrade !

Unwanted upgrade from o2 This is my Galaxy S3, I bought this phone to replace my iPhone 4S, but I guess I am just a lifelong iPhone user, and may just order the new iPhone 5. Running on the latest Android 4.1.1 Jelly Bean software. All new ready to use with peace of mind with a 24mth warrenty. Comes boxed with everything, great phone and I do love the huge, bright super hd amoled screen. i may also have a few cases to chuck in + screen protectors + samsung flip case white + extra battery all worth £50 Collection is more than welcome however I would require cash on collection due to the PayPal fraud that is currently out there.
