Iphone 4 16gb Unlocked** Brilliant Condition ?

Check This IPHONE 4 Which Is UNLOCKED To Any Networks when on jailbreak. I had an O2 sim in, when the phone was originally on Orange/Tmobile. I Bought It From A Friend In December, And Ever Since It Has Been Perfect. However I Just Received An Iphone 4s Which Is My Reason For Sale. You Can Collect From Manchester Or Blackburn Area As I Am In Either Place Frequently. Any More Queries, Please Let Me Know On 07920850826. Good Luck! Many Thanks
