Maybe I'm paranoid maybe not... Guy has offered me their new 4S for my S3 (Yes 4S might have been out for awhile but I want one and it would make me happy lol). They have produced this serial DQGJ9CG7DTD2. On apple's site it says not yet activated which for me rings alarm bells. Trading a completely unused phone? Firstly it could be stolen from a shop or they could have taken out a contract, not used it yet then will claim its lost. Any thoughts...anyone else experienced similar?
