Hi Guys, so here's the crack. I've just taken out a new contract for a Samsung Galaxy S3 on a 18 month contract with Vodafone UK. The phone was free and the phone cost me nothing it was free with the contract. I have now been offered, in exchange for my White Samsung Galaxy S3 16GB, a 32GB iPhone 4S mint condition and unlocked, with 100 pound on top from the guy who has offered me the deal. (For you guys across the pond that's 160 ish dollars I think and an iPhone 4s 32gb for my Samsung galaxy s3) Here is my dilemma. Originally I wanted the iPhone 4S, but Vodafone wanted I think 140 pound for a 16gb model or 240 pound for a 32gb model, whereas a Samsung galaxy s3 was free. So this looks like a _really_ good deal right? But I have now fallen in love with my S3, but my head is saying, this is a deal not to be missed. Thoughts and input?
