Iphone 4s 32gb and iphone 4 16gb ?

Hi I have 2 iphones, 1x iphone 4s (32gb, black on 02) and 1x iphone 4 (16gb black on 3) and I am looking to transfer the remainder of the contracts due to a move abroad. The 4s is on 02 and can be upgraded in July 2013, the contract is £41 a month and gives you 1200 mins, unlimited texts and 500mb of data. The iphone 4s is just under a year old and has the usual wear and tear, but is in good condition. Total amount for the phone and contract is £492, this would be cheaper that a 2 year contract. The iphone 4 is on 3 and has 16mths remaining, the monthly charge is £35 and is on the one plan which gives unlimited texts and minutes and 1gb of data. The phone is about 7 months old and has the usual wear and tear. Total amount for the phone and contract is £560, this would be cheaper that a 2 year contract. Would anyone be interested in taking over the contracts, if so you would need to attend a 3 and 02 shop with me to transfer everything legally. Cheers Karl
